LoadError：无法加载此类文件 - 等等

Question

I am seeing this error, after upgrading to ruby 2.7.2 using ruby-build and rbenv on Mac OS BigSur.

Rails 6.0.3.5

≻ bundle exec rspec spec/acceptance/roles_spec.rb    
An error occurred while loading ./spec/acceptance/roles_spec.rb. - Did you mean?
                    rspec ./spec/acceptance/users_spec.rb


Failure/Error: require File.expand_path('../config/environment', __dir__)

LoadError:
  cannot load such file -- etc

Application.rb:5 - require "rails"

I have tried to create a completely new Rails project with same rails and ruby version, which didn't have the same problem running rake rspec.

This issue got solved after doing the following:

• Delete bootsnap cache:

  rm -rf tmp/cache/bootsnap*

This might have solved the issue, but I did also:

• Use ruby 2.7.3
• bundle update bootsnap simplecov Installing bootsnap 1.7.5 (was 1.7.2)
