rails-rspec error cannot load such file -- rspec/core/formatters/progress_formatter
Ruby on-Rails-4Rspec RailsRuby on-Rails-4 Problem Overview
I've broken my rails-rspec. I switched to a different gemset to run a 3rd party test. When I returned to my 2.3.0(default) gemset, I had the following errors.
running rspec gets:
/.rvm/gems/ruby-2.3.0/gems/activesupport-4.2.0/lib/active_support/dependencies.rb:274:in `require': cannot load such file -- rspec/core/formatters/progress_formatter (LoadError)
running rails generate rspec:install returns:
Could not find generator 'rspec:install'. Maybe you meant 'devise:install' or ...
I have tried uninstalling and reinstalling, but errors persist.
Running rspec -v returns:
- rspec-core 3.6.0
- rspec-expectations 3.6.0
- rspec-mocks 3.6.0
- rspec-rails 3.6.1
- rspec-support 3.6.0
It seems that ruby cannot find rspec-core. I have tried the workaround from this post without success. Thank you in advance for any insight you might provide.

Ruby on-Rails-4 Solutions
Solution 1 - Ruby on-Rails-4
Running bundle exec rspec solved it for me.
Solution 2 - Ruby on-Rails-4
Running bundle clean --force did the trick for me, turns out there's some outdated gem in my system
Solution 3 - Ruby on-Rails-4
I learned this from Victor Hazbun - expert on CodeMentor and Egghead.io:
Run gem list | grep rspec and pay attention to any gems that list multiple versions.
Then run gem uninstall ______ for each of those versions (removing ALL of the versions of each).
Then run bundle afterward. This will sync your versions with the versions in your gemfile.
Solution 4 - Ruby on-Rails-4
I was getting the error below in a rails app and none of the solutions here worked for me.
gems/rspec-core-3.8.0/lib/rspec/core/formatters.rb:210:in `require': cannot load such file -- rspec/core/formatters/progress_formatter (LoadError)
Emptying the gemset and re-installing did.
This assumes you are using rvm and a .ruby-gemset at the root of your app.
$ rvm gemset empty <name-of-gemset>
$ bundle install
Solution 5 - Ruby on-Rails-4
I think you should try
bundle exec rspec:install
Solution 6 - Ruby on-Rails-4
I was trying to make a contribution to CocoaPods and was getting the same error when I was doing rspec foo_spec.rb. Turns out they were NOT using rpsec at all. They seem to have had a special test runner:
> CocoaPods uses bacon as a test runner. To run all tests, use bundle exec rake spec in the root of the project. If you want to run a specific test instead, use bundle exec bacon spec/[folder]/[name]_spec.rb
For more on that see here
Solution 7 - Ruby on-Rails-4
If you run the specs from RubyMine, you can specific the RSpec version in Run Configuration.
