RSpec can't find Cucumber gem

Question

When running rspec I get the following error:

no such file to load -- cucumber-rails

Missing these required gems:
  cucumber-rails  

You're running:
  ruby 1.8.7.174 at /usr/bin/ruby1.8
  rubygems 1.3.5 at /home/amurmann/.gem/ruby/1.8, /usr/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

I set up the test environemnt to require rspec, rspec-rails as well as cucumber. These are all installed:

 - [F] has_many_polymorphs 
    - [R] activerecord 
 - [I] rspec >= 1.2.0
 - [I] rspec-rails >= 1.2.0
    - [I] rspec >= 1.3.0
    - [R] rack >= 1.0.0
 - [I] factory_girl 
 - [I] webrat >= 0.4.3
    - [I] nokogiri >= 1.2.0
    - [R] rack >= 1.0
    - [I] rack-test >= 0.5.3
       - [R] rack >= 1.0
 - [I] cucumber-rails 
    - [I] cucumber >= 0.6.2
       - [I] term-ansicolor >= 1.0.4
       - [I] treetop >= 1.4.2
          - [I] polyglot >= 0.2.5
       - [I] polyglot >= 0.2.9
       - [R] builder >= 2.1.2
       - [I] diff-lcs >= 1.1.2
       - [I] json_pure >= 1.2.0
 - [I] database_cleaner >= 0.4.3

I = Installed
F = Frozen
R = Framework (loaded before rails starts)

I already reinstalled both cucumber and rspec, but the error persists.

Thank you very much for any help!

Answer 1

hmm, you did use sudo gem install cucumber-rails to install the gem right? Sometimes that throws 'stuff' off.

Answer 2

I am having the same problem on windows:xp. Running slightly newer gems, but most of the environment is same as the original post.

Answer 3

OK, I figured it out myself:

The spec file I was running had a "require 'cucumber_rails'". I don't know if and why I put that there or if it was put there by some script. I removed this and now everything works.

I am not sure why this caused a problem, but now it works. If someone knows why this causes trouble, I would be happy about an explanation.

Answer 4

Guys, just follow the Wiki instructions.
