Unresolved specs during Gem::Specification.reset:

Question

When launching Guard, I\'m getting this output:

$ guard
WARN: Unresolved specs during Gem::Specification.reset:
             


        

Answer 1

FYI:

gem cleanup

worked for me.

$ gem cleanup

Answer 2

I use gem list gem-name; gem uninstall gem-name to clean the gem one by one because of the dependency. After that, the error does not show again.

Answer 3

Remember, if you want to use guard, you have to add gem guard to Gemfile.

group :developement, :test do
  gem 'guard'
end

Then, run

bundle install

I hope this can help you.
