I'm using Linux. Does anyone know what's wrong, or what I could do to fix it? Any help would be appreciated , but I think I'm going to end up starting from scratch with the Treehouse VM on my Windows PC.

Ok, so I finally got it working.

in the Gemfile I changed the rspec gem to this:

gem 'rspec-rails', '< 3.0.0'

then in the terminal I ran:

bundle

then:

rails generate rspec:install

And I'm not sure if this is required but I ran this:

bundle binstubs rspec-core --force

And now rspec works, but it needs to have bundle exec prepended to the command, like this:

bundle exec rspec spec/features/todo_lists/create_spec.rb

I think this might have also changed my spec_helper.rb file, so just check and put " require 'capybara/rspec' " in there if it's missing.

Yeah, if you just write rspec, it will execute the version that is installed on your system, which is 3.x. Bundle exec will use the specific version from the Gemfile.

You are using RSpec 3.2 and the videos use the old RSpec 2.x. So your test code will have to look a little bit different unless you downgrade your rspec gem.

I found someting similar on StackOverflow. Would it work like this:

gem "rspec", "2.0"

in my gemfile, and then run:

bundle update rspec

Maybe :). You won't know until you try. Make sure you use git to reverse the changes if something breaks.

Perhaps this would be better, to get the last version before 3.0: gem "rspec", "< 3"

So I've got this in my gemfile:

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug'

  # Access an IRB console on exception pages or by using <%= console %> in views
  gem 'web-console', '~> 2.0'

  # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring
  gem 'spring'

  gem 'rspec', '< 3.0.0'
end

And I saved. But I'm not sure what to do in the terminal. I've tried bundle update rspec, and got a message that said "could not find rspec", then I tried just bundle, which did...something. I'm getting the same error message as before though when I try rspec ../create_spec.rb and when I do rspec -v, it says 3.2.1.

Oh, sorry, use rspec-rails. So:

gem 'rspec-rails', '< 3'

And then do the whole whole bundle install.

I added: gem 'rspec-rails', '< 3.0.0'.

ran bundle ran rails generate rspec:install ran bundle binstubs rspec-core --force ran bundle exec rspec spec/features/todo_lists/create_spec.rb

but I get the same answer when I enter bin/rspec spec/features/todo_lists/create_spec.rb

I get the same thing

It's got to be: bundle exec rspec spec/features/todo_lists/create_spec.rb

bundle exec makes it use the older version that you installed. I'm not sure if you need the "bin/" before rspec, I do not.
