RVM can't set ruby as default

Question

I have no idea why but RVM can't seem to change the default Ruby. I'm using Oh My Zsh and tried everything I've found but nothing seems to work.

➜  Sites  rvm use 2.0.0 --default
Using /Users/anahkiasen/.rvm/gems/ruby-2.0.0-p247
➜  Sites  rvm list
rvm rubies

=* ruby-2.0.0-p247 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

➜  Sites  rvm reload && rvm list
RVM reloaded!

rvm rubies

 * ruby-2.0.0-p247 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

Now the Ruby is set as default but RVM doesn't load it as "current", which means it does not load the gemsets that are affiliated to it.

➜  Sites  rvm use 2.0.0
Using /Users/anahkiasen/.rvm/gems/ruby-2.0.0-p247
➜  Sites  gem list

*** LOCAL GEMS *** 

Nothing.

I have no .bashrc nor .bash_profile. There is no RVM reference in my .zprofile and here is my .zshrc :

# Path to your oh-my-zsh configuration.
ZSH=$HOME/.oh-my-zsh

# Set name of the theme to load.
ZSH_THEME="robbyrussell"
DEFAULT_USER="anahkiasen"

# Uncomment following line if you want red dots to be displayed while waiting for completion
COMPLETION_WAITING_DOTS="true"

# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
plugins=(git bower brew composer gem laravel sublime)

## RVM and Rubygems
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

source $ZSH/oh-my-zsh.sh

I've tried swapping the above two lines, tried moving the RVM loading into .zprofile, nothing. Everytime I open a new instance of the terminal, the default is gone. It loads the correct ruby, meaning if I do ruby -v I get the version I want, but for RVM it's not loaded and thus I have none of the gemsets.

I've also tried rvm --default use 2.0.0, rvm use 2.0.0@develop --default but same result.

I've reinstalled RVM, I've set recursively the permissions of the .rvm folder to the current user, nothing.

I'm kind of desperate at that point.

I don't get it. You reload RVM and your version is still marked as the default. — sevenseacat, Aug 03 '13 at 12:42
Yes my bad, but nonetheless – if it actually is the default, shouldn't it be loaded as current when opening a new session ? — Maxime Fabre, Aug 03 '13 at 12:44
That's the weird part : it is loaded in the environment but not for RVM, which means it doesn't load the gemsets affiliated to it, will edit the main post with more details. — Maxime Fabre, Aug 03 '13 at 12:51
are you sure when you reloaded RVM, it didnt just change to the default gemset, and you were working in a different gemset? — sevenseacat, Aug 03 '13 at 12:55

As you are using OH-MY-ZSH you might be hitting issue similar to this: https://github.com/robbyrussell/oh-my-zsh/pull/1359

RVM has a "fix" function, run:

rvm get head --auto-dotfiles

It will reorganize your dot files - it is important to read the output and follow instructions.

Make sure to use login shell for best effect.

Unfortunately that didn't change anything, it replaced the lines in the correct dotfiles but the bug persists. – Maxime Fabre Aug 04 '13 at 01:11
did you get info about forced `PATH` and follow instructions to remove it? – mpapis Oct 28 '14 at 08:25
My ruby version changes back to system installed old ruby when I run `source ~/.zshrc`. I fix it by commenting out the PATH setting line in .zshrc as the pull request suggested. – lingceng Jul 02 '15 at 06:54

Ah ha !! I just faced the same problem and resolved it eventually.

Let me reiterate my issue: Everytime i start my terminal, i had to first do a bundle install each time. Then i figured, Its not correct. So i tried sourcing my zshrc.

So everytime i had to do source ~/.zshrc or simply zsh also did the same and my gemset would get identified. Ofcourse assuming RVM and all other dependencies are installed correctly

Finally i figured i needed to do the following:

$ vim ~/.zlogin

The contents of the .zlogin should be

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
zsh   #to initiate zsh (you could also replace this with 'source ~/.zshrc')

This resolved my problem. Now everytime i start my terminal, my defaults are all set.

Let me know if this works for you.
