Public Instance Methods

consider_local?() click to toggle source

Indicated, based on the requested domain, if local gems should be considered.

 
               # File rubygems/dependency_installer.rb, line 111
def consider_local?
  @domain == :both or @domain == :local
end

consider_remote?() click to toggle source

Indicated, based on the requested domain, if remote gems should be considered.

 
               # File rubygems/dependency_installer.rb, line 119
def consider_remote?
  @domain == :both or @domain == :remote
end

install(dep_or_name, version = Gem::Requirement.default) click to toggle source

Installs the gem dep_or_name and all its dependencies. Returns an Array of installed gem specifications.

If the :prerelease option is set and there is a prerelease for dep_or_name the prerelease version will be installed.

Unless explicitly specified as a prerelease dependency, prerelease gems that dep_or_name depend on will not be installed.

If c-1.a depends on b-1 and a-1.a and there is a gem b-1.a available then c-1.a, b-1 and a-1.a will be installed. b-1.a will need to be installed separately.
