    The base directory where this environment will be created.

  • dirname (String) —

    The directory name for this environment.

  • options (Hash) (defaults to: {}) —

    An additional set of options for this environment. The semantics of this environment may depend on the environment implementation.

#status ⇒ Symbol

This method is abstract.

Determine the current status of the environment.

This can return the following values:

* :absent - there is no module installed
