  • 0

I want to switch between different projects, and one part of that is changing rubies and gemsets via rvm. RVM works great for me by itself, but when I put a call to it into a shell script, I get:

fork: Resource temporarily unavailable

Here’s the output from rvm info. Let me know if there’s any other info I can give that would be useful.

$ rvm info

    I use RVM in shell scripts and it works fine. One thing that might explain why you’re unable to, is your version is old. The current version is 1.2.8, and you’re on 1.0.9.

    RVM updates often, so it’s a good idea to update it every couple weeks at least. In the current RVM we’d use rvm get head to update, but I’m not sure it that was the same in 1.0.9. If not try rvm help update.
