Installing Ruby gems not working with Home Brew

Question

The gems I install via sudo gem install ... can\'t be executed (I get a command not found). They seem to install into /usr/local/Cellar/

Answer 1

I think this evolve a bit.

Just add

export PATH=/usr/local/opt/ruby/bin:$PATH

To your .bashrc (or .bash_profile, .zshrc/.bashrc, .. – whatever you use).

If you have a problem with ruby itself

brew unlink ruby
brew link ruby
