Notes for Linux ( DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu 10.10" )
NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X)
This is the *original* / standard Ruby Language Interpreter
'ree' represents Ruby Enterprise Edition
'rbx' represents Rubinius
bash >= 3.2 is required
curl is required
git is required (>= 1.7 recommended)
patch is required (for ree and some ruby-head's).
If you wish to install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.
If you wish to have the 'pretty colors' again,
set 'export rvm_pretty_print_flag=1' in ~/.rvmrc.
dependencies:
# For RVM
rvm: bash curl git
# For Ruby (MRI & ree) you should install the following OS dependencies:
ruby: /usr/bin/apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev
# For JRuby (if you wish to use it) you will need:
jruby: /usr/bin/apt-get install curl g++ openjdk-6-jre-headless
jruby-head: /usr/bin/apt-get install ant openjdk-6-jdk
# In addition to ruby: dependencies,
ruby-head: subversion
# For IronRuby (if you wish to use it) you will need:
ironruby: /usr/bin/apt-get install curl mono-2.0-devel
You must now complete the install by loading RVM in new shells.
1) Place the folowing line at the end of your shell's loading files
(.bashrc or .bash_profile for bash and .zshrc for zsh),
after all PATH/variable settings:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
You only need to add this line the first time you install rvm.
2) Ensure that there is no 'return' from inside the ~/.bashrc file,
otherwise rvm may be prevented from working properly.
This means that if you see something like:
'[ -z "$PS1" ] && return'
then you change this line to:
if [[ -n "$PS1" ]] ; then
# ... original content that was below the '&& return' line ...
fi # <= be sure to close the if at the end of the .bashrc.
# This is a good place to source rvm v v v
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
EOF - This marks the end of the .bashrc file
Be absolutely *sure* to REMOVE the '&& return'.
If you wish to DRY up your config you can 'source ~/.bashrc' at the bottom of your .bash_profile.
Placing all non-interactive (non login) items in the .bashrc,
including the 'source' line above and any environment settings.
3) CLOSE THIS SHELL and open a new one in order to use rvm.
WARNING: you have a 'return' statement in your ~/.bashrc
This could cause some features of RVM to not work.
This means that if you see something like:
'[ -z "$PS1" ] && return'
then you change this line to:
if [[ -n "$PS1" ]] ; then
# ... original content that was below the '&& return' line ...
fi # <= be sure to close the if at the end of the .bashrc.
# This is a good place to source rvm v v v
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
EOF - This marks the end of the .bashrc file
Even if you are using zsh you should still adjust the ~/.bashrc
If you have any questions about this please visit
#rvm on irc.freenode.net.
Installation of RVM to /home/ca/.rvm/ is complete.
biboyatienza,
Thank you very much for using RVM! I sincerely hope that RVM helps to
make your work both easier and more enjoyable.
If you have any questions, issues and/or ideas for improvement please
join#rvm on irc.freenode.net and let me know, note you must register
(http://bit.ly/5mGjlm) and identify (/msg nickserv <nick> <pass>) to
talk, this prevents spambots from ruining our day.
My irc nickname is 'wayneeseguin' and I hang out in #rvm typically
~09:00-17:00EDT and again from ~21:00EDT-~23:00EDT
If I do not respond right away, please hang around after asking your
question, I will respond as soon as I am back. It is best to talk in
#rvm itself as then other users can help out should I be offline.
Be sure to get head often as rvm development happens fast,
you can do this by running 'rvm get head' followed by 'rvm reload'
or opening a new shell
w⦿‿⦿t
~ Wayne
Adjust .bashrc:
biboyatienza:~$ gedit .bashrc
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
Test RVM:
biboyatienza:~$ type rvm | head -1
rvm is a function
