Jekyll build failed: Liquid Exception: cannot load such file -- yajl - ruby

Question

Just recently skanked my PC, and I've not used Jekyll in a while, or indeed Ruby, however after thinking I'd set up everything correctly, when I try and run...
jekyll build or
jekyll serve
I get this error:
Generating... Liquid Exception: cannot load such file -- yajl/2.0/yajl i

I think it's related to pygments.rb somehow. If i remove the first post that has the syntax highlighting demo, the build works. I've attemped to update pgyments to 0.5.4 but this seemed to make no different. I think got an error that pygments.rb is locked to 0.3.4:
Fetching gem metadata from https://rubygems.org/.......
Fetching gem metadata from https://rubygems.org/..
Resolving dependencies...
You have requested:
pygments.rb ~> 0.5.4
The bundle currently has pygments.rb locked at 0.3.7.
Try running `bundle update pygments.rb`
Can anyone shed any light on this? It's driving me nuts. Running Ruby 2.0.0p353.

Answer 1

I did following
gem install rouge
and then
added following line in the _config.yml
highlighter: rouge
I found this solution from following page's last comment

Answer 2

I encountered a similar problem today when trying to setup Octopress/Jekyll.
Here is the solution I found.
Step 1
Go to your ruby gems directory.
In my case it's located at C:/Ruby21/lib/ruby/gems/2.1.0/gems
Look for yajl.
You will see a folder called yajl-ruby-1.1.0-x86-mingw32
You may or may not see one called yajl-ruby-1.2.1
The one with a -ruby-1.1.0-x86-mingw32 tail is the default. And leads to the error.
What we want to use is the other version
Step 2
If you do not have the none mingw32 version, run
gem install yajl-ruby
This will install the latest version.
In my case the latest version was 1.2.1
Step 3
Change the default from the mingw32 version to the current version.
To do so, go to your website's gemfile.lock file
Find the line that says yajl-ruby (1.1.0-x86-mingw32)
and change it to yajl-ruby (1.2.1)
or the respective version you downloaded
Step 4
That's it. It should work now.

Answer 3

Yajl itself is a “small event-driven (SAX-style) JSON parser written in ANSI C.” You are supposed to install it on your Windows box (I’m not sure if there are binary downloads available, possibly you are to download sources and compile them with your preferred C compiler) before trying to install yajl-ruby gem, which is simply the binding to it.
Another option is to install Ruby development kit, refer to this manual for detailed explanation.
