When executing a bash shell script I am using ruby 1.9.3. Then, within the script, I want to switch to JRub (I’m using rvm). I tried switching to JRuby by doing rvm use jruby within the script, but this didn’t work, it said:
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.
./run.sh: line 10: jruby: command not found
When I do type rvm | head -n1 at the command prompt, I get: rvm is a function. So I’m not sure of the problem. I thought it might be because I installed JRuby using sudo (sudo rvm install jruby). So I ran the shell script again using sudo. Again I received the error.
How can I switch rubies from within a bash shell script with rvm?
Thanks
I ended up adding this to the line before:
as explained in this thread (sorry – though I was aware of this thread before, I didn’t quite grasp it):
RVM doesn't switch Rubies
