How can I install Jekyll on Ubuntu 10.04 Server?

Question

The definitive guide to installing Jekyll seems to be http://wiki.github.com/mojombo/jekyll/install where it says:

gem install jekyll

I am getting an

ERROR:  could not find gem jekyll locally or in a repository

regardless of whether I run that command as superuser or not.
gem env Returns the following:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.2.0

  - REMOTE SOURCES:

I have also tried specifying github as the source with no luck. What else should I be trying?

Answer 1

You are using a very outdated version of RubyGems.

First, update the sources:

$ gem sources --clear-all
$ gem sources --add http://rubygems.org
$ gem sources --add http://gems.github.com

Then try to install it.

You should also login as a superuser and update the RubyGems version. The current release is 1.3.7.
