DESCRIPTION
perlbrew is a program to automate the building and installation of perl
in the users HOME. At the moment, it installs everything to
"~/perl5/perlbrew", and requires you to tweak your PATH by including a
bashrc/cshrc file it provides. You then can benefit from not having to
run 'sudo' commands to install cpan modules because those are installed
inside your HOME too. It's a completely separate perl environment.
INSTALLATION
To use "perlbrew", it is required to install "curl" or "wget" first.
"perlbrew" depends on one of this two external commmands to be there in
order to fetch files from the internet.
The recommended way to install perlbrew is to run these statements in
your shell:
curl -L http://xrl.us/perlbrewinstall | bash
After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and
you should follow the instruction on screen to setup your ".bashrc" or
".cshrc" to put it in your PATH.
The downloaded perlbrew is a self-contained standalone program that
embeds all non-core modules it uses. It should be runnable with perl 5.8
or later versions of perl.
This installer also installs a packed version of "patchperl" to
"~/perl5/perlbrew/bin", which is required to build old perls.
The directory "~/perl5/perlbrew" will contain all install perl
executables, libraries, documentations, lib, site_libs. If you need to
install "perlbrew", and the perls it brews, into somewhere else because,
say, your HOME has limited quota, you can do that by setting a
"PERLBREW_ROOT" environment variable before running the installer:
export PERLBREW_ROOT=/opt/perlbrew
curl -L http://xrl.us/perlbrewinstall | bash
You may also install perlbrew from CPAN:
cpan App::perlbrew
However, please make sure not to run this with one of the perls brewed
with perlbrew. It's the best to turn perlbrew off before you run that,
if you're upgrading.
perlbrew off
cpan App::perlbrew
You should always use system cpan (like /usr/bin/cpan) to install
"App::perlbrew" because then it will be installed under a system PATH
like "/usr/bin", which is not affected by perlbrew "switch" or "use"
command.
However, it is still recommended to let "perlbrew" install itself. It's
easier, and it works better.
USAGE
Please read the program usage by running
perlbrew
(No arguments.) To read a more detailed one:
perlbrew -h
PROJECT DEVELOPMENT
perlbrew project uses github
<http://github.com/gugod/App-perlbrew/issues> and RT
<https://rt.cpan.org/Dist/Display.html?Queue=App-perlbrew> for issue
tracking. Issues sent to these two systems will eventually be reviewed
and handled.
