Dependabot can't parse your Gemfile

[dependabot-preview]

Dependabot couldn't parse the Gemfile found at /Gemfile.

The error Dependabot encountered was:

Dependabot only supports uninterpolated string arguments to eval_gemfile. Got `Pathname(File.dirname(File.absolute_path(__FILE__))).join('datalayer', 'Gemfile')`
