rvm

DESCRIPTION:

RVM is the Ruby enVironment Manager (rvm).

It manages Ruby application environments and switching between them.

Installation

curl -L get.rvm.io | bash -s stable [--ruby] [--rails] [--trace]

stable

Install stable RVM, good for servers.

–ruby

Additionally install latest ruby version (MRI).

–rails

Install gem rails into default gemset (also installs ruby if not selected).

–trace

Print trace of the installation, gist output when you have problems.

More details here: rvm.io/rvm/install/

Usage

rvm [Flags] [Options] Action [Implementation[,Implementation[,...]]

Flags

–default

with 'rvm use X', sets the default ruby for new shells to X.

–debug

Toggle debug mode on for very verbose output.

–trace

Toggle trace mode on to see EVERYTHING rvm is doing.

–force

Force install, removes old install & source before install.

–summary

Used with rubydo to print out a summary of the commands run.

–latest

with gemset –dump skips version strings for latest gem.

–gems

with uninstall/remove removes gems with the interpreter.

–docs

with install, attempt to generate ri after installation.

–reconfigure

Force ./configure on install even if Makefile already exists.

Options

-v|–version

Emit rvm version loaded for current shell

-l|–level

patch level to use with rvm use / install

–bin

path for binaries to be placed (~/.rvm/bin/)

-S

Specify a script file to attempt to load and run (rubydo)

-e

Execute code from the command line.

–gems

Used to set the 'gems_flag', use with 'remove' to remove gems

–archive

Used to set the 'archive_flag', use with 'remove' to remove archive

–patch

With MRI Rubies you may specify one or more full paths to patches

for multiple, specify comma separated:

--patch /.../.../a.patch[%prefix],/.../.../.../b.patch

'prefix' is an optional argument, which will be bypassed to the '-p' argument of the 'patch' command. It is separated from patch file name with '%' symbol.

-C|–configure

custom configure options. If you need to pass several configure options then append them comma separated:

-C --...,--...,--...

–nice

process niceness (for slow computers, default 0)

–ree-options

Options passed directly to ree's './installer' on the command line.

–with-rubies

Specifies a string for rvm to attempt to expand for set operations.

Action

(Note: for most actions, 'rvm help action-name' may provide more information.)

usage

show this usage information

version

show the rvm version installed in rvm_path

use

setup current shell to use a specific ruby version

reload

reload rvm source itself (useful after changing rvm source)

implode

(seppuku) removes the rvm installation completely.

This means everything in $rvm_path (~/.rvm || /usr/local/rvm).

This does not touch your profiles. However, this means that you must manually clean up your profiles and remove the lines which source RVM.

get

{head,stable} upgrades rvm to latest head or stable version.

Check 'rvm help get' for more details.

(If you experience bugs try this first with head version, then ask for help in #rvm on irc.freenode.net and hang around)

reset

remove current and stored default & system settings.

(If you experience odd behavior try this second)

info

show the current environment information for current ruby

current

print the current ruby version and the name of any gemset being used.

debug

show info plus additional information for common issues

install
