Class Method Details
.activate(dep, *requirements) ⇒ Object
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.

Finds the user's home directory. -- Some comments from the ruby-talk list regarding finding the home directory:

it should fallback to USERPROFILE and HOMEDRIVE + HOMEPATH (at
least on Win32).
