[rspec-users] uninitialized constant ActionView::Helpers::TagHelper::ERB (NameError)
I am a new to ruby and rails and am trying to refactor some code with
rspec and have run into a problem that has stumped me for a few days and
I have searched google and ruby/rails forums to no avail so I really
hope somebody can help me out with this problem which I think may be
caused by a rails config problem. Anyway, I used ''rails new
myapp'' to
make a new rails project and then I copied the files (just a few files
each containing a class) I want to refactor into "myapp/app" and after
running the command ''rspec collector_helper_spec.rb'' I get the
following
error:

Can anyone explain to me why ERB cannot be found? From the information
I found about ERB it is part of ActiveSupport and I ran the command "gem
install activesupport" and afterwards I see activesupport installed when
I issue the command "gem list". If anyone can point me in the right
direction either by explaining what I am doing wrong or telling me about
some documentation to read or something that would be great.

But let''s give it a shot: 1. Make sure you have this in your Gemfile: gem ''rspec-rails'', :group => [:development, :test] 2. Install the bundle bundle install After you do this, ''gem list rspec'' should include rspec, rspec-core, rspec-expectations, rspec-mocks, and rspec-rails. 3. Install rspec rails generate rspec:install 4. Move app/collector_helper_spec.rb to spec/helpers/collector_helper_spec.rb and make sure the following appears at the top: require "spec_helper" Now try running ''rake spec'' and if you still run into the any problems, please post (preferably on http://gist.github.com/ or http://pastie.org/) the backtrace and code in spec/helpers/collector_helper_spec.rb, app/helpers/collector_helper.rb.
