If you’re working with the mongrel_service gem then you should know that right now there’s a few kinks in the system.
Here’s a quick rundown of the setup for Rails on Windows from scratch:
Download the One Click Ruby Installer and run the setup program.
Open a command prompt and type these commands:
gem update --system gem install rails gem install mongrel gem install win32-service -v '0.5.2' gem install mongrel_service
The key to this is that the win32-service gem is currently broken, so switching to a previous version (0.5.2) works great for us. Credit for this goes to Luis Laverna, the creator of the mongrel_service gem. See the discussion.
