Forum: Ruby 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-instal...

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...

Some might say...not the best choice.

Leave the system ruby alone, and install the latest version of ruby:

http://www.ruby-lang.org/en/downloads/

Then install rubygems, which is the program that lets you install gems:

http://rubygems.org/

Then try to install a gem.

I'm using Mac OS X 10.8 and followed the articles instructions up to 
where he started to export the settings for sudo which I don't like to 
do and unless you're doing something as a system admin on a server, I'd 
leave the sudo out of the installation. Just add the proxy information 
as he pointed out in the article and then use the command: gem install 
<name of gem>.

If there's some reason you need to use sudo, I have little doubt the 
instructions he posted would be incorrect.
