"Missing these required gems: rspec-rails" in ruby 1.9

i get the above error when running rake. I tried switching rails 2.3.3 with 2.3.2 but it didn't help.

here are my gems: actionmailer (2.3.2) actionpack (2.3.2) activerecord (2.3.2) activeresource (2.3.2) activesupport (2.3.2) builder (2.1.2) cucumber (0.3.98) diff-lcs (1.1.2) hoe (2.3.3) nokogiri (1.3.3) polyglot (0.2.8) rack (1.0.0) rails (2.3.2) rake (0.8.7) rspec (1.2.8) rspec-rails (1.2.7.1) rubyforge (1.0.4) term-ansicolor (1.0.4) test-unit (1.2.3) treetop (1.3.0) webrat (0.5.3)

and here is the error after typing rake:

It's exactly what it says. Do:

gem install rspec-rails

(or if you're on a Mac, sudo gem install rspec-rails).

change the config.gem lines for rspec/rspec-rails in your test.rb to:

config.gem "rspec", :lib => false config.gem "rspec-rails", :lib => false

that should solve your problem

thank you, it works! what is the reason for this error?

7

rails tries to require 'rspec' and 'rspec-rails'. but the rspec library is 'spec' and the rspec-rails is 'spec/rails'. :lib => 'spec' / :lib => 'spec/rails' would work too, but since you only want to load the rspec/rails libs when you are actually running specs, and you usually require 'spec/rails' in your spec_helper.rb anyway, you can use :lib => false so rails doesn't require the rspec libs at all.

thank you!
