errors after adding the gem rubocop-rspec

[Gusarov2k]

Hello! Help Wanted ? After adding the gem rubocop-rspec and running rspec, an error appears. I was looking for the answer in google but the proposed solutions did not help me. Thanks for your help!

$ bundle exec rspec spec/models

An error occurred while loading ./spec/models/card_spec.rb.
Failure/Error: require File.expand_path('../config/environment', __dir__)

Rubocop depends on the parser gem, most likely it's failing to bring it along with itself. Given that you added rubocop and did not otherwise have issues with RSpec, I'd suggest this is most likely an issue with Rubocop or rubocop-rspec, and you should follow up with them.
