When trying to run rspec, I get “uninitialized constant ActiveModel”

Question

When I run rspec spec I get the following:

/usr/local/lib/ruby/gems/1.9.1/gems/rspec-rails-2.7.0/lib/rspec/rails/extensions/active_record/base.rb:26:in `         


        

Answer 1

Found this thread while debugging the same symptoms. Here is another reason for the error: I had run

rspec --init

but had failed to run

rails generate rspec:install

Doing the latter fixed the problem.
