RVM is not working in ZSH

Question

I'd like to try out the ZSH shell on my Mac, but I also do a lot of Ruby and Rails development, so I use RVM quite a bit too. The problem is that I can't seem to get RVM to work in ZSH, and it's working fine in the default Bash shell:

> zsh
> rvm 1.9.2
> ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
> which ruby
/usr/bin/ruby

I can definitely confirm that RVM is installed, as well as ruby 1.9.2 under RVM; I use it all the time in Bash. Running an rvm list in ZSH shows this, interestingly:

rvm rubies

   ruby-1.8.7-p302 [ x86_64 ]
=> ruby-1.9.2-p0 [ x86_64 ]

This is happening on both my iMac and MacBook Pro. I am using OS X 10.6.6 on both, ZSH 4.3.9 on the iMac (4.3.10 on the laptop). Nothing fancy like oh-my-zsh just yet.

I tried looking at the documentation on RVM's website, but nothing helped me there.

Answer 1

Do you have this line in your ~/.zshrc?

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" 

Answer 2

Note March 2014:

With latest RVM, the following line:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" 

isn't needed anymore, and it shouldn't be in your ~/.zshrc.

Documentation has been updated in RVM documentation with Zsh:

Make sure in iTerm2 Preferences: Login shell option is set (do not use Command option). This is required for RVM to work.

If you are still getting rvm is not a function errors on iTerm, try:

rvm get stable --auto-dotfiles

Answer 3

Note November 2014

The rvm installation instructions warn that .zshrc doesn't include $PATH when setting PATH, thus replacing PATH's contents without regard for what already exists in PATH.

To remedy this I now append PATH to have .rvm/bin and then prepend $PATH at the beginning of setting PATH on the second line:

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

export PATH=$PATH:"/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin:/usr/local/mysql/bin:/opt/local/bin"

I had the same problem, I solved using this after "ruby on rails" installation:

echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.zshrc

and

source ~/.zshrc

Answer 5

I use zsh, and had [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" in my .zshrc file, but was getting a parse error:404.

When I moved that line to the .profile file, the error stopped. It seems it was conflicting with something in my .zshrc file, and perhaps running it in .profile avoided the .zshrc file incompatibility. I haven't been able
