Where do gems install?
Look at your gem environment.
In a terminal run gem env
You should see an entry INSTALLATION DIRECTORY, but there is also GEM PATHS which is where it's loading all your gems from in your current environment.
Rvm
$ rvm gemdirOr you can check:
echo $GEM_HOMEBundler
$ bundle show --pathsFor specific gem:
$ bundle show 'gem_name'Gem
$ gem envFor specific gem:
$ gem which 'gem_name'
To see the default installation directory, run
gem env gemdir
If you want to change the default installation directory (for example, to ~/.gem/ruby/2.1.0), add this line to ~/.bashrc
export GEM_HOME=~/.gem/ruby/2.1.0
And you also need to make sure ~/.gem/ruby/2.1.0/bin is in your PATH environment variable to use the commands provided by gem packages. If not, add this line to ~/.bashrc
export PATH=$PATH:~/.gem/ruby/2.1.0/bin
