Jekyll install on Windows error?

Question

I'm not very knowledgeable with Ruby, but I want to try Jekyll. I'm using Windoows 7 64-bit and I have Ruby 2.0.0p451 installed and I installed the related development kit. When I enter ruby dk.rb install, I get the following messages:

[INFO] Skipping existing gem override for 'C:/Ruby200-x64'
[WARN] Skipping existing DevKit helper library for 'C:/Ruby200-x64'

and then when I try to install Jekyll with gem install Jekyll, I get the following error:

ERROR: Error installing jekyll:
ERROR: Failed to build the gem native extension.

If you need more from the message I got I can provide it.

Answer 1

I found the solution on the rubyinstaller troubleshooting page on GitHub (go figure) The command REG QUERY "HKCU\Software\Microsoft\Command Processor" output an AutoRun message, which was the culprit. After deleting it with REG DELETE "HKCU\Software\Microsoft\Command Processor" AutoRun I was able to install Jekyll. Finally!
