Ruby on Rails 3 Tutorial Book Question

Im following the PDF version of this book and keep having an issue with different versions of gems being compatible. I had to skip the TDD section all together because I couldnt get a compatible version of rspec installed. Im now having the same problem with downloading a compatible version of blueprint-css. I dont want to have to skip anymore content. Is there an easier way to get all the correct versions of your gems? Im a React dev and very new to Rails so im unsure of how to navigate. Please advise!!

I totally understand your frustration — gem version mismatches can be one of the trickiest parts of following along with older Rails materials.

One of the most frustrating aspects of working with older Rails assets is dealing with gem version discrepancies, and I completely get that.
