#
# This is a pre-compiled source code for the cpanm (cpanminus) program.
# For more details about how to install cpanm, go to the following URL:
#
# https://github.com/miyagawa/cpanminus
#
# Quickstart: Run the following command and it will install itself for
# you. You might want to run it as a root with sudo if you want to install
# to places like /usr/local/bin.
#
# % curl -L https://cpanmin.us | perl - App::cpanminus
#
# If you don't have curl but wget, replace `curl -L` with `wget -O -`.
# DO NOT EDIT -- this is an auto generated file
# This chunk of stuff was generated by App::FatPacker. To find the original
# file's code, look for the end of this BEGIN block or the string 'FATPACK'

It appears your cpanm executable was installed via `perlbrew install-cpanm`.
cpanm --self-upgrade won't upgrade the version of cpanm you're running.
Run the following command to get it upgraded.
perlbrew install-cpanm
DIE
You are running cpanm from the path where your current perl won't install executables to.
Because of that, cpanm --self-upgrade won't upgrade the version of cpanm you're running.
cpanm path : $0
Install path : $Config{installsitebin}
It means you either installed cpanm globally with system perl, or use distro packages such
as rpm or apt-get, and you have to use them again to upgrade cpanm.

Usage: cpanm [options] Module [...]
Try `cpanm --help` or `man cpanm` for more options.
USAGE
Usage: cpanm [options] Module [...]
Options:
-v,--verbose Turns on chatty output
-q,--quiet Turns off the most output
--interactive Turns on interactive configure (required for Task:: modules)
-f,--force force install
-n,--notest Do not run unit tests
--test-only Run tests only, do not install
-S,--sudo sudo to run install commands
--installdeps Only install dependencies
--showdeps Only display direct dependencies
--reinstall Reinstall the distribution even if you already have the latest version installed
--mirror Specify the base URL for the mirror (e.g. http://cpan.cpantesters.org/)
--mirror-only Use the mirror's index file instead of the CPAN Meta DB
-M,--from Use only this mirror base URL and its index file
--prompt Prompt when configure/build/test fails
-l,--local-lib Specify the install base to install modules
-L,--local-lib-contained Specify the install base to install all non-core modules
--self-contained Install all non-core modules, even if they're already installed.
--auto-cleanup Number of days that cpanm's work directories expire in. Defaults to 7
Commands:
--self-upgrade upgrades itself
--info Displays distribution info on CPAN
--look Opens the distribution with your SHELL
-U,--uninstall Uninstalls the modules (EXPERIMENTAL)
-V,--version Displays software version
Examples:
cpanm Test::More # install Test::More
cpanm MIYAGAWA/Plack-0.99_05.tar.gz # full distribution path
cpanm http://example.org/LDS/CGI.pm-3.20.tar.gz # install from URL
cpanm ~/dists/MyCompany-Enterprise-1.00.tar.gz # install from a local file
cpanm --interactive Task::Kensho # Configure interactively
cpanm . # install from local directory
cpanm --installdeps . # install all the deps for the current directory
cpanm -L extlib Plack # install Plack and all non-core deps into extlib
cpanm --mirror http://cpan.cpantesters.org/ DBI # use the fast-syncing mirror
cpanm -M https://cpan.metacpan.org App::perlbrew # use only this secure mirror and its index
You can also specify the default options in PERL_CPANM_OPT environment variable in the shell rc:
export PERL_CPANM_OPT="--prompt --reinstall -l ~/perl --mirror http://cpan.cpantesters.org"
Type `man cpanm` or `perldoc cpanm` for the more detailed explanation of the options.

WHOA THERE! It looks like you've got some fancy dashes in your commandline!
These are *not* the traditional -- dashes that software recognizes. You
probably got these by copy-pasting from the perldoc for this module as
rendered by a UTF8-capable formatter. This most typically happens on an OS X
terminal, but can happen elsewhere too. Please try again after replacing the
dashes with normal minus signs.

FATAL: The local::lib --self-contained flag has never worked reliably and the
original author, Mark Stosberg, was unable or unwilling to maintain it. As
such, this flag has been removed from the local::lib codebase in order to
prevent misunderstandings and potentially broken builds. The local::lib authors
recommend that you look at the lib::core::only module shipped with this
distribution in order to create a more robust environment that is equivalent to
what --self-contained provided (although quite possibly not what you originally
thought it provided due to the poor quality of the documentation, for which we
apologise).

cpanm --from https://cpan.metacpan.org/ Plack # use only the HTTPS mirror
=head1 COMMANDS
=over 4
=item (arguments)
Command line arguments can be either a module name, distribution file,
local file path, HTTP URL or git repository URL. Following commands
will all work as you expect.
cpanm Plack
cpanm Plack/Request.pm
cpanm MIYAGAWA/Plack-1.0000.tar.gz
cpanm /path/to/Plack-1.0000.tar.gz
cpanm http://cpan.metacpan.org/authors/id/M/MI/MIYAGAWA/Plack-0.9990.tar.gz
cpanm git://github.com/plack/Plack.git
Additionally, you can use the notation using C<~> and C<@> to specify
version for a given module. C<~> specifies the version requirement in
the L<CPAN::Meta::Spec> format, while C<@> pins the exact version, and
is a shortcut for C<~"== VERSION">.
cpanm Plack~1.0000 # 1.0000 or later
cpanm Plack~">= 1.0000, < 2.0000" # latest of 1.xxxx
cpanm Plack@0.9990 # specific version. same as Plack~"== 0.9990"
The version query including specific version or range will be sent to
L<MetaCPAN> to search for previous releases. The query will search for
BackPAN archives by default, unless you specify C<--dev> option, in
which case, archived versions will be filtered out.
For a git repository, you can specify a branch, tag, or commit SHA to
build. The default is C<master>
cpanm git://github.com/plack/Plack.git@1.0000 # tag
cpanm git://github.com/plack/Plack.git@devel # branch
=item -i, --install
Installs the modules. This is a default behavior and this is just a
compatibility option to make it work like L<cpan> or L<cpanp>.
=item --self-upgrade
Upgrades itself. It's just an alias for:
cpanm App::cpanminus
=item --info
Displays the distribution information in
C<AUTHOR/Dist-Name-ver.tar.gz> format in the standard out.
=item --installdeps
Installs the dependencies of the target distribution but won't build
itself. Handy if you want to try the application from a version
controlled repository such as git.
cpanm --installdeps .
=item --look
Download and unpack the distribution and then open the directory with
your shell. Handy to poke around the source code or do manual
testing.
=item -h, --help
Displays the help message.
=item -V, --version
Displays the version number.
=back
=head1 OPTIONS
You can specify the default options in C<PERL_CPANM_OPT> environment variable.
=over 4
=item -f, --force
Force install modules even when testing failed.
=item -n, --notest
Skip the testing of modules. Use this only when you just want to save
time for installing hundreds of distributions to the same perl and
architecture you've already tested to make sure it builds fine.
Defaults to false, and you can say C<--no-notest> to override when it
is set in the default options in C<PERL_CPANM_OPT>.
=item --test-only
Run the tests only, and do not install the specified module or
distributions. Handy if you want to verify the new (or even old)
releases pass its unit tests without installing the module.
Note that if you specify this option with a module or distribution
that has dependencies, these dependencies will be installed if you
don't currently have them.
=item -S, --sudo
Switch to the root user with C<sudo> when installing modules. Use this
if you want to install modules to the system perl include path.
Defaults to false, and you can say C<--no-sudo> to override when it is
set in the default options in C<PERL_CPANM_OPT>.
=item -v, --verbose
Makes the output verbose. It also enables the interactive
configuration. (See --interactive)
=item -q, --quiet
Makes the output even more quiet than the default. It only shows the
successful/failed dependencies to the output.
=item -l, --local-lib
Sets the L<local::lib> compatible path to install modules to. You
don't need to set this if you already configure the shell environment
variables using L<local::lib>, but this can be used to override that
as well.
=item -L, --local-lib-contained
Same with C<--local-lib> but with L<--self-contained> set. All
non-core dependencies will be installed even if they're already
installed.
For instance,
cpanm -L extlib Plack
would install Plack and all of its non-core dependencies into the
directory C<extlib>, which can be loaded from your application with:
use local::lib '/path/to/extlib';
Note that this option does B<NOT> reliably work with perl installations
supplied by operating system vendors that strips standard modules from perl,
such as RHEL, Fedora and CentOS, B<UNLESS> you also install packages supplying
all the modules that have been stripped. For these systems you will probably
want to install the C<perl-core> meta-package which does just that.
=item --self-contained
When examining the dependencies, assume no non-core modules are
installed on the system. Handy if you want to bundle application
dependencies in one directory so you can distribute to other machines.
=item --exclude-vendor
Don't include modules installed under the 'vendor' paths when searching for
core modules when the C<--self-contained> flag is in effect. This restores
the behaviour from before version 1.7023
=item --mirror
Specifies the base URL for the CPAN mirror to use, such as
C<http://cpan.cpantesters.org/> (you can omit the trailing slash). You
can specify multiple mirror URLs by repeating the command line option.
You can use a local directory that has a CPAN mirror structure
(created by tools such as L<OrePAN> or L<Pinto>) by using a special
URL scheme C<file://>. If the given URL begins with `/` (without any
scheme), it is considered as a file scheme as well.
cpanm --mirror file:///path/to/mirror
cpanm --mirror ~/minicpan # Because shell expands ~ to /home/user
Defaults to C<http://www.cpan.org/>.
=item --mirror-only
Download the mirror's 02packages.details.txt.gz index file instead of
querying the CPAN Meta DB. This will also effectively opt out sending
your local perl versions to backend database servers such as CPAN Meta
DB and MetaCPAN.
Select this option if you are using a local mirror of CPAN, such as
minicpan when you're offline, or your own CPAN index (a.k.a darkpan).
=item --from, -M
cpanm -M https://cpan.metacpan.org/
cpanm --from https://cpan.metacpan.org/
Use the given mirror URL and its index as the I<only> source to search
and download modules from.
It works similar to C<--mirror> and C<--mirror-only> combined, with a
small difference: unlike C<--mirror> which I<appends> the URL to the
list of mirrors, C<--from> (or C<-M> for short) uses the specified URL
as its I<only> source to download index and modules from. This makes
the option always override the default mirror, which might have been
set via global options such as the one set by C<PERL_CPANM_OPT>
environment variable.
B<Tip:> It might be useful if you name these options with your shell
aliases, like:
alias minicpanm='cpanm --from ~/minicpan'
alias darkpan='cpanm --from http://mycompany.example.com/DPAN'
=item --mirror-index
B<EXPERIMENTAL>: Specifies the file path to C<02packages.details.txt>
for module search index.
=item --cpanmetadb
B<EXPERIMENTAL>: Specifies an alternate URI for CPAN MetaDB index lookups.
=item --metacpan
Prefers MetaCPAN API over CPAN MetaDB.
=item --cpanfile
B<EXPERIMENTAL>: Specified an alternate path for cpanfile to search for,
when C<--installdeps> command is in use. Defaults to C<cpanfile>.
=item --prompt
Prompts when a test fails so that you can skip, force install, retry
or look in the shell to see what's going wrong. It also prompts when
one of the dependency failed if you want to proceed the installation.
Defaults to false, and you can say C<--no-prompt> to override if it's
set in the default options in C<PERL_CPANM_OPT>.
=item --dev
B<EXPERIMENTAL>: search for a newer developer release as well. Defaults to false.
=item --reinstall
cpanm, when given a module name in the command line (i.e. C<cpanm
Plack>), checks the locally installed version first and skips if it is
already installed. This option makes it skip the check, so:
cpanm --reinstall Plack
would reinstall L<Plack> even if your locally installed version is
latest, or even newer (which would happen if you install a developer
release from version control repositories).
Defaults to false.
=item --interactive
Makes the configuration (such as C<Makefile.PL> and C<Build.PL>)
interactive, so you can answer questions in the distribution that
requires custom configuration or Task:: distributions.
Defaults to false, and you can say C<--no-interactive> to override
when it's set in the default options in C<PERL_CPANM_OPT>.
=item --pp, --pureperl
Prefer Pure perl build of modules by setting C<PUREPERL_ONLY=1> for
MakeMaker and C<--pureperl-only> for Build.PL based
distributions. Note that not all of the CPAN modules support this
convention yet.
=item --with-recommends, --with-suggests
B<EXPERIMENTAL>: Installs dependencies declared as C<recommends> and
C<suggests> respectively, per META spec. When these dependencies fail
to install, cpanm continues the installation, since they're just
recommendation/suggestion.
Enabling this could potentially make a circular dependency for a few
modules on CPAN, when C<recommends> adds a module that C<recommends>
back the module in return.
There's also C<--without-recommend> and C<--without-suggests> to
override the default decision made earlier in C<PERL_CPANM_OPT>.
Defaults to false for both.
=item --with-develop
B<EXPERIMENTAL>: Installs develop phase dependencies in META files or
C<cpanfile> when used with C<--installdeps>. Defaults to false.
=item --with-configure
B<EXPERIMENTAL>: Installs configure phase dependencies in C<cpanfile>
when used with C<--installdeps>. Defaults to false.
=item --with-feature, --without-feature, --with-all-features
B<EXPERIMENTAL>: Specifies the feature to enable, if a module supports
optional features per META spec 2.0.
cpanm --with-feature=opt_csv Spreadsheet::Read
the features can also be interactively chosen when C<--interactive>
option is enabled.
C<--with-all-features> enables all the optional features, and
C<--without-feature> can select a feature to disable.
=item --configure-timeout, --build-timeout, --test-timeout
Specify the timeout length (in seconds) to wait for the configure,
build and test process. Current default values are: 60 for configure,
3600 for build and 1800 for test.
=item --configure-args, --build-args, --test-args, --install-args
B<EXPERIMENTAL>: Pass arguments for configure/build/test/install
commands respectively, for a given module to install.
cpanm DBD::mysql --configure-args="--cflags=... --libs=..."
The argument is only enabled for the module passed as a command line
argument, not dependencies.
=item --scandeps
B<DEPRECATED>: Scans the depencencies of given modules and output the
tree in a text format. (See C<--format> below for more options)
Because this command doesn't actually install any distributions, it
will be useful that by typing:
cpanm --scandeps Catalyst::Runtime
you can make sure what modules will be installed.
This command takes into account which modules you already have
installed in your system. If you want to see what modules will be
installed against a vanilla perl installation, you might want to
combine it with C<-L> option.
=item --format
B<DEPRECATED>: Determines what format to display the scanned
dependency tree. Available options are C<tree>, C<json>, C<yaml> and
C<dists>.
=over 8
=item tree
Displays the tree in a plain text format. This is the default value.
=item json, yaml
Outputs the tree in a JSON or YAML format. L<JSON> and L<YAML> modules
need to be installed respectively. The output tree is represented as a
recursive tuple of:
[ distribution, dependencies ]
and the container is an array containing the root elements. Note that
there may be multiple root nodes, since you can give multiple modules
to the C<--scandeps> command.
=item dists
C<dists> is a special output format, where it prints the distribution
filename in the I<depth first order> after the dependency resolution,
like:
GAAS/MIME-Base64-3.13.tar.gz
GAAS/URI-1.58.tar.gz
PETDANCE/HTML-Tagset-3.20.tar.gz
GAAS/HTML-Parser-3.68.tar.gz
GAAS/libwww-perl-5.837.tar.gz
which means you can install these distributions in this order without
extra dependencies. When combined with C<-L> option, it will be useful
to replay installations on other machines.
=back
=item --save-dists
Specifies the optional directory path to copy downloaded tarballs in
the CPAN mirror compatible directory structure
i.e. I<authors/id/A/AU/AUTHORS/Foo-Bar-version.tar.gz>
If the distro tarball did not come from CPAN, for example from a local
file or from GitHub, then it will be saved under
I<vendor/Foo-Bar-version.tar.gz>.
=item --uninst-shadows
Uninstalls the shadow files of the distribution that you're
installing. This eliminates the confusion if you're trying to install
core (dual-life) modules from CPAN against perl 5.10 or older, or
modules that used to be XS-based but switched to pure perl at some
version.
If you run cpanm as root and use C<INSTALL_BASE> or equivalent to
specify custom installation path, you SHOULD disable this option so
you won't accidentally uninstall dual-life modules from the core
include path.
Defaults to true if your perl version is smaller than 5.12, and you
can disable that with C<--no-uninst-shadows>.
B<NOTE>: Since version 1.3000 this flag is turned off by default for
perl newer than 5.12, since with 5.12 @INC contains site_perl directory
I<before> the perl core library path, and uninstalling shadows is not
necessary anymore and does more harm by deleting files from the core
library path.
=item --uninstall, -U
Uninstalls a module from the library path. It finds a packlist for
given modules, and removes all the files included in the same
distribution.
If you enable local::lib, it only removes files from the local::lib
directory.
If you try to uninstall a module in C<perl> directory (i.e. core
module), an error will be thrown.
A dialog will be prompted to confirm the files to be deleted. If you pass
C<-f> option as well, the dialog will be skipped and uninstallation
will be forced.
=item --cascade-search
B<EXPERIMENTAL>: Specifies whether to cascade search when you specify
multiple mirrors and a mirror doesn't have a module or has a lower
version of the module than requested. Defaults to false.
=item --skip-installed
Specifies whether a module given in the command line is skipped if its latest
version is already installed. Defaults to true.
B<NOTE>: The C<PERL5LIB> environment variable have to be correctly set
for this to work with modules installed using L<local::lib>, unless
you always use the C<-l> option.
=item --skip-satisfied
B<EXPERIMENTAL>: Specifies whether a module (and version) given in the
command line is skipped if it's already installed.
If you run:
cpanm --skip-satisfied CGI DBI~1.2
cpanm won't install them if you already have CGI (for whatever
versions) or have DBI with version higher than 1.2. It is similar to
C<--skip-installed> but while C<--skip-installed> checks if the
I<latest> version of CPAN is installed, C<--skip-satisfied> checks if
a requested version (or not, which means any version) is installed.
Defaults to false.
=item --verify
Verify the integrity of distribution files retrieved from PAUSE using
CHECKSUMS and SIGNATURES (if found). Defaults to false.
=item --report-perl-version
Whether it reports the locally installed perl version to the various
web server as part of User-Agent. Defaults to true unless CI related
environment variables such as C<TRAVIS>, C<CI> or C<AUTOMATED_TESTING>
is enabled. You can disable it by using C<--no-report-perl-version>.
=item --auto-cleanup
Specifies the number of days in which cpanm's work directories
expire. Defaults to 7, which means old work directories will be
cleaned up in one week.
You can set the value to C<0> to make cpan never cleanup those
directories.
=item --man-pages
Generates man pages for executables (man1) and libraries (man3).
Defaults to true (man pages generated) unless C<-L|--local-lib-contained>
option is supplied in which case it's set to false. You can disable
it with C<--no-man-pages>.
=item --lwp
Uses L<LWP> module to download stuff over HTTP. Defaults to true, and
you can say C<--no-lwp> to disable using LWP, when you want to upgrade
LWP from CPAN on some broken perl systems.
=item --wget
Uses GNU Wget (if available) to download stuff. Defaults to true, and
you can say C<--no-wget> to disable using Wget (versions of Wget older
than 1.9 don't support the C<--retry-connrefused> option used by cpanm).
=item --curl
Uses cURL (if available) to download stuff. Defaults to true, and
you can say C<--no-curl> to disable using cURL.
Normally with C<--lwp>, C<--wget> and C<--curl> options set to true
(which is the default) cpanm tries L<LWP>, Wget, cURL and L<HTTP::Tiny>
(in that order) and uses the first one available.
=back
=head1 ENVIRONMENT VARIABLES
=over 4
=item PERL_CPANM_HOME
The directory cpanm should use to store downloads and build and test
modules. Defaults to the C<.cpanm> directory in your user's home
directory.
=item PERL_CPANM_OPT
If set, adds a set of default options to every cpanm command. These
options come first, and so are overridden by command-line options.
