Hello,

I’ve just installed Ruby Gems on my OS X machine. Now I’d like to test  
whether it works or not without downloading a gem (I wouldn’t need it  
anyways). Is there a way to verify that my installation works?

Thank you very much in advance.

on terminal :

~\> gem list -r

# =\> r stands for remote

# =\> u’ll get the installable list of remotely available gems

~\> gem list -l

# =\> l stands for local

# =\> u’ll get the allready installed gems

~\> gem env

# =\> speaks by itseld 😉

~\> gem\_server

# point a browser to [http://localhost:8808/](http://localhost:8808/)

# =\> u’ll get RDoc
