Dependabot couldn't find a Gemfile for this project.

Dependabot requires a Gemfile to evaluate your project's current Ruby dependencies. It had expected to find one at the path: /Gemfile.

If this isn't a Ruby project, or if it is a library, you may wish to disable updates for it from within Dependabot.
