This topic has been driving me nuts for a while now, and I'd like to be able to figure out what's going wrong. I use zsh with screen in my terminal, and have been for a while. However, for whatever reason, it appears that on login, my installation of RVM doesn't get loaded by default. Ruby is correctly set to the version installed by RVM (1.9.3), but the rest of the environment doesn't get loaded:

~/Desktop => ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]
~/Desktop => rails -v
Rails is not currently installed on this system. To get the latest version, simply type:

    $ sudo gem install rails

You can then rerun your "rails" command.
~/Desktop => rvm reload
RVM reloaded!
~/Desktop => rails -v
Rails 3.2.1

I have no idea what's going wrong, and by all accounts, it doesn't seem like anything should be going wrong. My screenrc file correctly uses the login shell with shell -$SHELL, but it doesn't seem to have any effect (unfortunately, this is the only thing that appears to have fixed other people's installations of RVM within screen, and it's what the docs suggest making sure you have set, but it doesn't seem to make a difference for me).

I'm running on Mac OS X 10.7.3, and my login shell is set to /bin/zsh. I don't use oh-my-zsh. My zshrc file is as follows (sorry about the length - I'm sure not all of it is relevant, but I don't want to leave any potentially useful information out):

Weirdest of all, however, is that when I change my RVM sourcing line to [[ -s ~/.rvm/scripts/rvm ]] && source ~/.rvm/scripts/rvm && rvm reload, I see the message RVM reloaded!, but the environment still isn't set up. rails isn't recognized until I reload RVM again.

Any help with this would be much appreciated. Thanks!

have you tried with zsh 4.3.12 - we had many error reports with higher and lower versions –  mpapis Feb 19 '12 at 19:25
    
Using the system-provided zsh - version 4.3.11. I can try to install 4.3.12 via Homebrew if it would help. –  Itai Ferber Feb 19 '12 at 19:36
    
@mpapis Tried it, but using version 4.3.12 made no difference. –  Itai Ferber Feb 19 '12 at 19:52

After quite a bit of tinkering, rvm finally successfully loads its environment by default. Now, I don't know exactly what part of what I did fixed the issue, but hopefully, this will be of aid to someone.

Essentially, I went through and split up my zsh configuration into two files: the .zshenv file (which gets loaded by all programs) and the .zshrc file (which gets loaded by graphical programs). For those unfamiliar with how zsh works, these files are essentially analogs to .bash_profile and .bashrc.

This is a huge hack, but I just put this line into .bashrc as well as in .bash_profile:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 

With this, rvm use 1.93 and similar commands worked at both normal and screen prompts, no longer giving the rvm is not a function error. As long as this snippet is idempotent (i.e. has no ill effects due to being invoked twice or N times) this should be ok. And given that it is invoked on every login shell anyway, that is probably true. But let's see if that is the case...
