class Gem::Doctor - rubygems: Ruby Standard Library Documentation

# class Gem::Doctor

Cleans up after a partially-failed uninstall or for an invalid `Gem::Specification`.

If a specification was removed by hand this will remove any remaining files.

If a corrupt specification was installed this will clean up warnings by removing the bogus specification.

### Public Class Methods

new(gem_repository, dry_run = false) click to toggle source

Creates a new `Gem::Doctor` that will clean up `gem_repository`. Only one gem repository may be cleaned at a time.

If `dry_run` is true no files or directories will be removed.

    # File rubygems/doctor.rb, line 45
    def initialize(gem_repository, dry_run = false)
      @gem_repository = gem_repository
      @dry_run        = dry_run

      @installed_specs = nil
    end
