How to install Jekyll on mac osx 10.9 with ruby 2.0.0?

Question

I am trying to install Jekyll on my mac. My mac version is 10.9 and ruby version is 2.0.0. But when I used sudo gem install jekyll in my terminal, it went to mistake like this:

➜  ~  sudo gem install jekyll

ERROR:  Error installing jekyll:

I looked through here and tried many methods, but none of them work. How can I fix this?

Answer 1

It doesn't look like you have ruby installed / managed via rvm. I would definitely recommend rvm and homebrew on os x. They will save you a lot of headache.

Here is a good link on how to set that up:

Answer 2

it works with ruby-2.1.1 so you have to

rvm use ruby-2.1.1

and

sudo gem install jekyll

P.S. if you don't have rvm - install it before :)

Answer 3

You are using System ruby. Check out whether you have ruby install or not. For that you can use which ruby command and it will give some output likes

which ruby
/Users/amritdeepdhungana/.rvm/rubies/ruby-2.0.0-p353/bin/ruby

If you have not install it by following this guide. Or you can install it from rvm site.
