I’m working on an older Rails 2.3.8 application that is way too complicated and without tests to make it worth upgrading to Rails 3 or higher. Because of this we must use RSpec-Rails 1.3.4, with RSpec 1.3.2.

I was just trying to run a single test from the command line like so:

$ bundle exec rspec spec/models/post.rb

bundler: command not found: rspec

Install missing gem executables with `bundle install`

I tried to uninstall and reinstall the gems, but still it didn’t work. I am using RVM, so this might be part of why this command isn’t working.

It turns out that older versions of RSpec used ‘spec’ instead of ‘rspec’ as the executable name.
