Rails开发Mac OS或Windows

I am currently starting Ruby on Rails development and currently use Windows (XP or 7), but I find lots of cases where gems don't seem to do what they should or its a pain to install and use them under Windows, like twitter-bootstrap seems fine for Mac OS but I had to work out that sass-bootstrap was better for Windows. It just goes on and on, like today I cannot seem to get launchy to do its thing when RSpec testing, although I know that my lack of experience doesn't help.I am currently starting Ruby on Rails developme
