Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v1_9_3_392) is shown here.

These similar methods exist in v2_5_5:

activate(dep, *requirements) public

Activates an installed gem matching dep. The gem must satisfy requirements.

Returns true if the gem is activated, false if it is already loaded, or an exception otherwise.

Gem#activate adds the library paths in dep to $LOAD_PATH. Before a Gem is activated its required Gems are activated. If the version information is omitted, the highest version Gem of the supplied name is loaded. If a Gem is not found that meets the version requirements or a required Gem is not found, a Gem::LoadError is raised.

More information on version requirements can be found in the Gem::Requirement and Gem::Version documentation.
