Error installing RedCloth (4.2.9) on OS X 10.9.2

Question

I try to install Jekyll with pages, using enter link description here. The process stops when installing RedCloth (4.2.9): "Make sure that gem install RedCloth -v '4.2.9' succeeds before bundling."

The results below (I changed https in H due to url limitations in this Question). I run OS X 10.9.2

mikea:mego mikea$ ruby --version
ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]

Step 2 = OK

mikea:mego mikea$ sudo gem install bundler

Answer 1

I solved this by install rbenv with brew, and then install ruby 2.1.1 through rbenv. Finally change the ruby version to 2.1.1. Here is the command:

$brew update
$brew install rbenv
$rbenv install 2.1.1
$rbenv global 2.1.1

log out. Now you can try your 3 step.
