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 set --local 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}.)
