Installing ruby gem

ruby-talk

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...

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.

Some might say...not the best choice.

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

Download Ruby

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

solve the problem?

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.
