Error Installing Jekyll on Mac I'm trying to install Jekyll, a simple, blog-aware, static site generator.  When I attempted to run the terminal command gem install jekyll, I got this error:



I then tried to update my RubyGems, using the command sudo gem update --system.  That didn't work.  Hopefully, I don't have to re-install Ruby.  What a headache that would be!
Following Seth Warburton's steps on Install Jekyll in OSX Mavericks, try adding sudo to the install command:

sudo gem install jekyll


If you need to update or re-install Ruby, consider using an isolated edition via brew.
