bundle-doctor - Checks the bundle for common problems
bundle doctor [--quiet] [--gemfile=GEMFILE]
Checks your Gemfile and gem environment for common problems. If
    issues are detected, Bundler prints them and exits status 1. Otherwise,
    Bundler prints a success message and exits status 0.
Examples of common problems caught by bundle-doctor include:
  - Invalid Bundler settings
- Mismatched Ruby versions
- Mismatched platforms
- Uninstalled gems
- Missing dependencies
  - 
  
  - --quiet
- Only output warnings and errors.
- --gemfile=<gemfile>
- The location of the Gemfile(5) which Bundler should use. This defaults to
      a Gemfile(5) in the current working directory. In general, Bundler will
      assume that the location of the Gemfile(5) is also the project´s
      root and will try to find Gemfile.lock and vendor/cache
      relative to this location.
