I’m unable to install some gems in the plugin, for e.g. `google-protobuf`. This gem is dependency for `google-cloud-vision` gem.

Here’s a plugin trying to install it. [GitHub - fzngagan/gem-issue · GitHub](https://github.com/fzngagan/gem-issue)

> Successfully installed google-protobuf-3.13.0-universal-darwin
> 1 gem installed
> You are specifying the gem google-protobuf in /Users/faiz/discenv/discourse/plugins/gem-issue/plugin.rb, however it does not exist!
> Looked for: /Users/faiz/discenv/discourse/plugins/gem-issue/gems/2.6.3/specifications/google-protobuf-3.13.0.gemspec
>

The reason for this is that the `.gemspec` file’s name doesn’t match the `spec_file`’s name assumed in the code here.

IMO, this would happen probably only when using platform-specific gems as the platform name gets added to the gem name if its platform dependent. This is described here. [Specification Reference - RubyGems Guides](https://guides.rubygems.org/specification-reference/#platform=)
