ruby - rspec --init not working/ `mkd ir': Invalid argument - ./C: (Errno::EINVAL)

Question

I'm following codeschool's class on rspec. Installing worked fine. I made a file called rspec-zombie for the project. Fine. But when I tried rspec --init in powershell, I got an unholy error message. I'm under the impression there are supposed to be some files made inside the directory, which aren't there. It follows.

C:UsersRomanThe-Odin-Project
spec-zombie> rspec --init
  create   .rspec

Answer 1

Here's how I finally fixed this crap:

gem uninstall rspec
gem uninstall rspec-core rspec-expectations rspec-mocks rspec-support
gem install rspec -v 2.14.1

Basically, newer versions of rspec are broken on Windows. Don't use them. Do this and rspec works just fine.
