ruby - Trying to install rails- EISDIR error

Question

I'm new to programming and am trying to set up Ruby on Rails using Michael Hartl's tutorial via Terminal on a Mac running Snow Leopard, but I'm a bit stuck on this part. I've tried using rvm 1.9.2, without any luck, and haven't been able to find anything googling. Any help would be appreciated!

Thanks!

CZom$ gem install rails -v 3.2.3

/Users/CZom/.gemrc should be a user specific config file that gets loaded when executing the gem command. Sounds like in your case it is a directory instead. Rubygems is complaining therefore.

Try to rename /Users/CZom/.gemrc or remove it completely if it isn't needed.
