Refinery - NoMethodError: undefined method `spec' for nil:NilClass

When I was installing refinery 3.0.0, at the end of the bundle process the error:

NoMethodError: undefined method `spec' for nil:NilClass
An error occurred while installing refinerycms-core (3.0.0), and Bundler cannot continue.

was shown.

Solution

  • The solution was to install the latest version of bundler:

    gem install bundle

    I hope it helps
