The `gem-ctags` gem does not expose a library file (a file in lib) which matches that name. It is a RubyGems plugin, and so it doesn’t need to do that.
Contrast this with `gem which rails`, which, on my machine, shows this path: /Users/ryanbigg/.gem/ruby/2.3.1/gems/railties-5.0.0/lib/rails.rb Rails _does_ have a file to expose and so `gem which` works. Out of curiosity: why are you doing `gem which` in this case?
