Subject: installing ruby gem

Hi everyone,


I'm learning ruby and I'm trying to install gems but i had some trouble
installing gems:

$ sudo gem install ...
ERROR:  http://rubygems.org/ does not appear to be a repository
ERROR:  Could not find a valid gem … in any repository

I don't know what to do.

I've tried to follow instructions in this article:

    http://jacob.stanley.io/2010/10/27/sudo-gem-install-behind-a-proxy/

But unfortunately I saved changes to /etc/sudoers.tmp (although the
article that i mentioned tells to do the opposite).

Please can you help me?

my operating system is mac os x 10.7.4, my ruby version is 1.8.7 and the
result of $ which ruby is: /usr/bin/ruby

I really don't know what to do...
