RVM + Zsh "RVM is not a function, selecting rubies with 'rvm use ...' will not work"
I'll start by saying I'm not an expert at command-line, so I really only barely know what I'm doing.
I cannot get RVM and oh-my-zsh to play nice together. I've tried several different solutions posted around, some on SO, but nothing I have found seems to fix the issue.
Initially, someone else setup RVM on my machine. I later setup oh-my-zsh myself, and remember having a lot of trouble doing so.
My .zhsrc file is completely default except for these 2 lines
export PATH=$HOME/bin:/usr/local/bin:/usr/local/rvm/bin:$PATH
#pretty sure this line does nothing, although I've seen this fix around
# several places. I noticed that I don't seem to have an .rvm file in my
# home directory which would be an issue, but I have no idea how to
# go about correcting this.
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I added the /usr/local/rvm to the Path directive as zsh returns zsh: rvm command not found without it there. Otherwise most rvm command work, with the exception of rvm use which throws the following error:
RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.
I have ensured the profile preferences on my profile in iTerm2 are set to "Login Shell" as recommended by RVM
I have tried changing these preferences to the "Command" option and using the recommended /bin/bash/ --login as the command, however zsh no longer appears to work when this happens. Changing the command to /bin/zsh/ --login allows zsh to work again but does not solve the problem as I still get the "RVM is not a function" error when trying to run rvm use
The default ruby in RVM is set to 2.0.0. I can run ruby -v in my home folder and get the ruby version output which shows the default version.
Working on rails projects, I can run all rails commands IF the Gemfile specifies ruby 2.0.0, the default. However on a project that uses a different version, I get the following error:
Your Ruby version is 2.0.0, but your Gemfile specified 1.9.3
Then I cannot run rvm use 1.9.3 as it returns the above mentioned error.
How can I make zsh play nice with RVM?
Some info about my setup:
- Mac OSX 10.9.1 (Mavericks)
- iTerm2
- Zsh 5.0.2 with oh-my-zsh
- RVM 1.5.1
Answer
For me, I just had to add
source $HOME/.rvm/scripts/rvm
to my ~/.zshrc and it started working, after having the same error message as in this SO question.
