Ruby Question

rbenv ruby on rails global vs local vs shell

// Start background info.

I just want to install ruby on rails for development (OSX El Capitan).

Pain point:

ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

Solution: Installed rbenv to manage / modify a separate ruby.

rbenv is currently using my system ruby - so I've downloaded an identical version through rbenv install.

// end background info.

Actual Question: Do I set local, global or shell ruby version to the newly downloaded version?

Answer Source

Usually rbenv does the dirty work for you if loaded correctly, but if you need to change the global setting, you can always update it:

rbenv global 2.3.0

Then you can check that's properly applied with:

rbenv versions

The * indicates the currently active ruby. Test with:

ruby -v

That should be the version you're asking for.

Using rbenv is a lot better than the system ruby, so I hope it works out for you.
