It has been working fine, and then suddenly it thinks it is version 1.8.7 (the ruby that came with snow leopard), not 1.9.3 (the one running on rvm, and the one called in the shebang line.
It happened last night, the problem went away, and now it's back again. I have removed the stap line from my bash profile, quit terminal, put it back, quit terminal, restarted my machine. I am vexed I must admit.
Script:
#!/Users/ben/.rvm/bin/ruby-1.9.3-p0
puts RUBY_VERSION
Return: 1.8.7
Irb using rvm:
Using /Users/ben/.rvm/gems/ruby-1.9.3-p0
1.9.3p0 :001 > RUBY_VERSION
=> "1.9.3"
1.9.3p0 :002 >
It has been working fine, and then suddenly stopped, my .bash_profile:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
I would update your scripts to use
#!/usr/bin/env ruby
As the "shebang" so it simply grabs the current ruby command. This will enable you to rvm use ... whatever you like and the scripts don't need to be changed.
Chances are you have a .rvmrc file lying around somewhere that's switching you back to your system ruby. Take a look through the directories you are navigating through and see if you can find one.

I get an error when I run %x{rvm use #myapp} in ruby and irb. The error is "RVM is not a function, selecting rubies with 'rvm use ...' will not work".
Here's what I've tried:
1. the "rvm use #myapp" command works in OSX command prompt (using OSX Mavericks)
2. made sure RVM is the latest version.
3. reloaded RVM check RVM is a function in the command prompt
4. (still fails in irb and ruby's %x{})
5. According to some SO posts, I changed OSX terminal preferences from login shell to /bin/bash and /bin/bash --login. Quit, opened new terminal windows but all efforts were in vain.
6. checked .bash_profile for [[-s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
Any ideas on how I can get %x{rvm use #myapp} to work in ruby and irb?
What happens here is that the shell you had started ruby or irb with had rvm defined both as a function and added to PATH the function takes precedence in shell and it all worked fine, but when you open ruby or irb it is a new process and it inherits only environment variables which includes PATH and does not inherit functions, additionally running %x{} from ruby creates another shell process which is neither a login or interactive shell, and they respectively would make shell load ~/.bash_profile and ~/.bashrc.
Depending on what do you want to do you have few options, to execute another ruby/gem you can use rvm ... do ... for from %x{} like this:
rvm #myapp do ruby -e '...'
OR:
rvm #myapp do gem install ...
OR:
rvm #myapp do bundle install
it allows single command to run in the context of given ruby
Try this trick:
%x{bash -c 'source "$HOME/.rvm/scripts/rvm"; rvm use #myapp'}
However, you really can use rvm as you've specified because even if you've set up the rvm you then lost your session because your terminal will be closed. Try to setup your environment with session gem, and control bash session with it.
require 'session'
#myapp = 'ruby-1.8.7-p374'
bash = Session::Bash.new
stdout, stderr = bash.execute 'source "$HOME/.rvm/scripts/rvm"'
stdout, stderr = bash.execute "rvm use #{#myapp}"
puts stdout
# => Using /home/malo/.rvm/gems/ruby-1.8.7-p374
By using these commands
source ~/.rvm/scripts/rvm
rvm use 1.9.3 --default
The version in current session is 1.9.3 but when I close terminal and reopen ruby version comes back to 1.8.7.
Do I need to add something to the .bash_profile ?
Edit: I found the another way is when I reopen terminal everytime just type source .bash_profile. The version then is 1.9.3. Is there anyway to execute the .bash_profile permanently ?
Yes you need to add something to your bash profile. See here:
https://rvm.io/rvm/basics/
Quote:
The rvm installation documentation instructs you to put the following line at the very end of your bash profile:
# This loads RVM into a shell session
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
Create a file named .rvmrc with the text rvm use 1.9.3 --default.
We're treading into sysadmin waters here but one possible explanation might be because of how you're logging into your shell and your OS. See the discussion of what files are loaded by your shell here and what makes up a login vs. non-login shell here.
In Terminal, ruby -v gives me:
ruby 1.8.7 (2011-12-28 patchlevel 357) [universal-darwin11.0]
But if I type /bin/bash then ruby -v I get:
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]
I suspect this is something to do with my PATH config(s). My $PATH variable is different in both the above environments. There are other issues e.g. rvm won't run unless I go into bash mode.
For info, my ~/.bashrc contains:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
Looks like "login shell" is not enabled, you need to enable it in Terminal Emulator Preferences, sometimes it is needed to use /bin/bash --login.
There are also known issues with ZSH, but it seams to be unrelated.
Try which ruby from "terminal" and "/bin/bash". Your 1.9.3 is inside your ~/.rvm path.
Type rvm info. You should get a list of the settings for RVM.
In your ~/.bashrc OR ~/.bash_profile, you should have RVM's initialization code. If you don't you didn't install RVM completely and need to finish. Read all the instructions on the RVM installation page.
This was not due to a $PATH problem. What I've learned is that RVM cannot be run unless you change your default login shell to either Bash or ZSH. Just firing up Terminal in Mac won't work. You make the global change to using Bash like this:
chsh -s /bin/bash
(swap /bin/bash for whatever your bash path is, find out using which bash).
The RVM website does say that bash>=3.2.25 is a prerequisite, but doesn't say what that is or how to check whether you have it. It also advises you to run rvm requirements to check what you need - and you can't run this unless you change your shell (all quite confusing for somebody new to this).
Thanks to the replies above for getting me there in the end.

I use OSX Lion. I have installed RVM and have put this line in my .bash_profile file.
[[ -s "/Users/Anand/.rvm/scripts/rvm" ]] && source "/Users/Anand/.rvm/scripts/rvm" # This loads RVM into a shell session.
I installed ruby-1.9.2-p290 and set it as default rvm ruby with this command:
rvm use --default ruby-1.9.2-p290
And when I checked ruby-v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.2.0]
The problem is, every time I open a new terminal window or a tab, the default ruby is not getting set. The system ruby is instead getting used. ruby -v gives this:
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10.3.2]
This also happens with reading .rvmrc file in a ruby project. When I'm inside a project and when a new tab gets opened, it gets me into the project directory but is not setting ruby according to .rvmrc in that project. What should I do to fix this?
I got the problem. It was with $PATH. I have to put rvm related line in the .bash_profile as the last line.
Old .bash_profile
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
source $HOME/Dropbox/dotfiles/bashrc
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export PATH=/Library/PostgreSQL/9.0/bin:$PATH
New .bash_profile
source $HOME/Dropbox/dotfiles/bashrc
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export PATH=/Library/PostgreSQL/9.0/bin:$PATH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
And it worked. New windows and new tabs open up correctly with the default ruby i.e, ruby 1.9.2
I just fixed this very same issue. Turns out it was a path issue.
try this
➜ ~ which ruby
if you are getting /usr/bin/ruby, the path to your original ruby installation is overshadowing the default install in your RVM installation.
I added the path to RVM before the path (see below) to /usr/bin/ruby and it works as expected.
I use zsh as my shell, so I had to add this manually to my .zshrc
export PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting<br />
export PATH=$PATH:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
if you use bash
Your .bashrc probably looks like this
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
change it to this:
PATH=$HOME/.rvm/bin:$PATH # Add RVM to PATH for scripting
and make sure you .bash_profile has this:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
and you should be good to go.
Of course this means that your shell is going to look in your RVM directory first when looking for any command, but thats never caused any issues for me.
Question #1:
The command as listed is, you had switched '--default' and 'use'.
rvm --default use ruby-1.9.2-p290
Check if default is actually set:
$ rvm list default
Default Ruby (for new shells)
ruby-1.9.2-p290 [ x86_64 ]
Some other troubleshooting tips in case that doesn't work. Are you sure your bash profile file is being loaded? Try just having 'source "/Users/Anand/.rvm/scripts/rvm' instead of the check, maybe something is wrong with the path? Username does that begin with capital letter?
Question #2: You must cd into the directory with the .rvmrc file explicitly for the magic to happen. I suppose starting a console in a certain location doesn't trigger rvm. I run into this when using pushd and popd to switch between folders.
Try this first if rvm --default use doesn't work:
sudo rvm alias create default 1.9.2
In the TextMate RVM instructions the text it says to set TM_RUBY to /Users/wayne/.rvm/bin/textmate_ruby and in the image it shows it set to rvm-auto-ruby. I decided to set it to rvm-auto-ruby thinking that it would use RVM's default Ruby version.
When running Command R in the RSpec.bundle having TM_RUBY set to rvm-auto-ruby will result in a load error. When you set it to textmate_ruby it works.
The only problem here is that TextMate doesn't always use the default version of Ruby since it's hardcoded in that file.
/Users/jspooner/.rvm/bin/textmate_ruby:
#!/usr/bin/env bash
if [[ -s "/Users/jspooner/.rvm/environments/ruby-1.9.2-head" ]] ; then
source "/Users/jspooner/.rvm/environments/ruby-1.9.2-head"
exec ruby "$#"
else
echo "ERROR: Missing RVM environment file: '/Users/jspooner/.rvm/environments/ruby-1.9.2-head'" >&2
exit 1
fi
So two questions:
What should TM_RUBY=rvm-auto-ruby actually do?
Is there a way to have TextMate use the RVM default?
Setting TM_RUBY to your-path/rvm-auto-ruby
http://rvm.io/integration/textmate/
should load whatever ruby and gemset is indicated in the .rvmrc file located in the project and if none default to rvm default. I just got this working and it is very smooth. I did need to get the latest version of rvm
rvm get head
to make it work and restart Textmate. Hope that helps.
See your other, similar, question Rspec bundle is broken in TextMate and rvm.
To help others chasing this same issue, the solution seems to be at: RVM / Textmate doesnt recognize .rvmrc Options.
Basically you replace the ~/.rvm/bin/textmate_ruby soft link with a file. This is what I did:
cd ~/.rvm/bin
mv textmate_ruby old.textmate_ruby
Create a shell script called textmate_ruby in the same directory to replace the soft-link, using the following contents:
!/usr/bin/env sh
source ~/.rvm/scripts/rvm
cd .
exec ruby "$#"
chmod +x textmate_ruby
Before doing this change I'd see my system Ruby's version (1.8.7) displayed if I did CMD+R to run the following script in TextMate:
puts RUBY_VERSION
Evaluating the script using CMD+CNTRL+SHIFT+E gave me 1.9.2.
After switching to use that script both point to Ruby 1.9.2, so at least there's some consistency now. I don't see TextMate tracking my currently set RVM Ruby version yet; Instead it's using the default version set in RVM: rvm use 1.9.2 --default. This is still a step forward because I can control which Ruby TextMate uses by adjusting my --default.
If you decide you want to revert later, just rename, or delete, the script and reverse step 2 above.
