“RVM is not a function” error

Question

RVM is installed on my machine (running Mac OSX 10.6.8), correctly and it runs fine. The odd thing is that to run it, I have to use source ~/.rvm/scripts/rvm for ev

Answer 1

If you are using zsh as shell instead bash, you have to:

1.

vi ~/.zshrc 

2. Like Matt said, add:

if test -f ~/.rvm/scripts/rvm; then
   [ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
fi

3. Restart Terminall 4. Done!

rvm use 1.9.3

Wil work

Answer 2

Well, with mountain lion (10.8.3) what worked for me was editing /etc/profile

and adding the line mentioned before at the bottom of the file:

  if test -f ~/.rvm/scripts/rvm; then
        [ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
    fi

Answer 3

You have to source the RVM script into the current session because it makes changes to the shell environment - and it is absolutely impossible for that to be done from a child process. Your efforts at running RVM as an external command cannot succeed.

To actually fix this you have two choices:

1. Configure your terminal emulator to start a login shell, rather than a non-login shell, so that your .profile is loaded.
2. Modify .bashrc to source RVM instead, which works for non-login shells as well.

To do the second you can just add to ~/.bashrc:

if test -f ~/.rvm/scripts/rvm; then
    [ "$(type -t rvm)" = "function" ] || source ~/.rvm/scripts/rvm
fi

Answer 4

I had this issue when I became root. I tried many of the solutions above. What finally worked was exiting from root and being a regular user. Which is what I needed anyway.

Answer 5

I didn't understand what ~/.profile does correctly; I needed to change ~/.bash_profile instead. Problem solved!

Answer 6

You have to make some settings.

Open terminal and run this command.

source ~/.rvm/scripts/rvm

and then go to edit > Title and command and check Run command as login shell

and you are done. Now you don't need to specify source everytime.
