How do you install Jekyll on OSX?

Question

I was following the instructions here, so I ran gem install jekyll on my osx machine, and got the following:

WARNING:  Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
      /usr/bin aren't both writable.
WARNING:  You don't have /Users/erikvold/.gem/ruby/1.8/bin in your PATH,
      gem executables will not run.
ERROR:  Error installing jekyll:
liquid requires RubyGems version >= 1.3.7

But I don't see instructions on how to deal with this in the instructions above.

Answer 1

Try to update gem first:

$ gem update --system

In case you get permission errors, you must resort to sudo for this and all other gem commands:

$ sudo gem update --system
