          Bundler cannot continue installing #{spec.name} (#{spec.version}).
          The checksum for the downloaded `#{spec.full_name}.gem` does not match \
          the checksum given by the server. This means the contents of the downloaded \
          gem is different from what was uploaded to the server, and could be a potential security issue.

To resolve this issue:
          1. delete the downloaded gem located at: `#{spec.gem_dir}/#{spec.full_name}.gem`
          2. run `bundle install`

If you wish to continue installing the downloaded gem, and are certain it does not pose a \
          security issue despite the mismatching checksum, do the following:
          1. run `bundle config disable_checksum_validation true` to turn off checksum verification
          2. run `bundle install`

(More info: The expected SHA256 checksum was #{checksum.inspect}, but the \
          checksum for the downloaded gem was #{digest.inspect}.)
