I’ve done this so many times this week that I’m writing it down here where I can Google it later. What I’m looking for is the specific three commands you type to install rspec and rspec-rails as plugins into my rails project.

To find this data normally, I do this:

1. Go to http://rspec.info because that’s the URL I can remember.
2. Click on Spec::Rails in the menu bar.
3. Click on Install in THAT menu bar.
4. This takes you to a page that tells you that the Install instructions are no longer here, they’ve moved to http://wiki.github.com/dchelimsky/rspec/rails
5. Hooray! THIS is the page you want to be at. Sure enough, scroll down to see

Okay, now… ready for the kicker? This documentation is ALSO out of date. (There’s a crash bug in tag 1.2.9 when you call model.should be_valid.) As of this writing, if you clone the rspec-rails repo and examine the tags, you will see that 1.3.2 is available. So here’s the updated command. For now.

ruby script/plugin install git://github.com/dchelimsky/rspec.git -r 'refs/tags/1.3.2'
ruby script/plugin install git://github.com/dchelimsky/rspec-rails.git -r 'refs/tags/1.3.2'
ruby script/generate rspec

…But lately I just get the latest and it seems to work:

ruby script/plugin install git://github.com/dchelimsky/rspec.git
ruby script/plugin install git://github.com/dchelimsky/rspec-rails.git
ruby script/generate rspec
