Jekyll 1.4.3 is broken on Windows

Just a heads up: Jekyll released version 1.4.3 a few days ago, and it is completely broken on Windows — not even standard site builds will work. Make sure you force gem to install version 1.4.2 until the bug is fixed.

If you see this when building a site:

C:\Users\delan\Documents\GitHub\delan.github.io>jekyll serve -w
Configuration file: C:/Users/delan/Documents/GitHub/delan.github.io/_config.yml
            Source: C:/Users/delan/Documents/GitHub/delan.github.io
       Destination: C:/Users/delan/Documents/GitHub/delan.github.io/_site
      Generating... error: Invalid argument - C:/Users/delan/Documents/GitHub/de
lan.github.io/_site/C:. Use --trace to view backtrace

Do this:

gem uninstall jekyll
gem install jekyll --version "=1.4.2"
