我已经安装了一个gem - 但是在/ lib中找不到它

Question

I've installed a ruby gem using the command line. When I try gem list --local it clearly shows that the gem is clearly installed on my machine.

However I want to make changes according to the documentation. According to the documentation (using gem server and then http://localhost:8808/ ), I should look for the gem under /lib .

However I cannot find it anywhere on my machine - I looked using my mac's finder so that I can then edit it using textmate, but nada.

Any ideas? Where should I look for the gem so I can edit/use it? Thanks!

Answer 1

You need to use the -d flag to get detailed information.

gem list --local -d

For uglifier , for example

uglifier (1.3.0)

Installed at: /Users/deefour/.rbenv/versions/1.9.3-p327/gemsets/myapp

Answer 2

To find the location of a gem:

gem which <gemname>

For example with the debugger gem

gem which debugger

/opt/ruby/ruby-1.9.3-p392/lib/ruby/gems/1.9.1/gems/debugger-1.5.0/lib/debugger.rb
