Jekyll - Error Running 'Jekyll Serve'

EDIT: Found the answer (see my answer below!). It involves using version 1.4.2 instead of 1.4.3, so if anyone has any ideas on getting 1.4.3 working, that could be helpful as well. Thanks!

EDIT 2: Thanks to a comment below, it seems that 1.4.3 does have a problem when running on windows.

I have just setup jekyll on my windows 7 computer. I have ruby installed along with the dev pack.

I have run `gem install jekyll` and that completed with success. I have created a new site as per the jekyll documentation.

The problem I am experiencing happens when I try to run `jekyll serve`. Please find below the error output.

I have looked around but am a novice with ruby, so I have no idea what to look for or how to find the error here. Any help would be much appriciated.

Thanks,

I had the same problem on Ubuntu Precise 12.04. The issue was that I had ruby1.8 installed. I also had ruby1.9.1 installed. I removed ruby1.8, and then Jekyll installed fine.

Answering my own question, I managed to find a solution.

This appears to be a problem with Jekyll version 1.4.3. To fix the issue I uninstalled jekyll and installed version 1.4.2.

`gem uninstall jekyll`


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

Doing this and everything should work fine if you have the same issue as me on windows.

I guess this is because version 1.4.3 is new (released on 13th) and is unstable on windows.

Just came across the same issue with Jekyll's plugin "Category Archive Generator" (

Most likely you have a plugin - in the _plugins folder - which is using the File.join() method. e.g. `File.join('/', dest, @dir, @category_dir_name, 'index.html')`

Modify this by deleting the first element leaving you with `File.join(dest, @dir, @category_dir_name, 'index.html')`
