``Ruby_FIND_VIRTUALENV``
This variable defines the handling of virtual environments managed by
``rvm``. It is meaningful only when a virtual environment
is active (i.e. the ``rvm`` script has been evaluated or at least the
``MY_RUBY_HOME`` environment variable is set).
The ``Ruby_FIND_VIRTUALENV`` variable can be set to empty or
one of the following:
.. versionadded:: 3.18
* ``FIRST``: The virtual environment is used before any other standard
paths to look-up for the interpreter. This is the default.
* ``ONLY``: Only the virtual environment is used to look-up for the
interpreter.
* ``STANDARD``: The virtual environment is not used to look-up for the
interpreter (assuming it isn't still in the PATH...)
This variable defines the handling of virtual environments.
It can be left empty or be set to one of the following values:
* ``FIRST``: Virtual Ruby environments are searched for first,
then the system Ruby installation.
This is the default.
* ``ONLY``: Only virtual environments are searched
* ``STANDARD``: Only the system Ruby installation is searched.
Virtual environments may be provided by:
``rvm``
Requires that the ``MY_RUBY_HOME`` environment environment is defined.
``rbenv``
Requires that ``rbenv`` is installed in ``~/.rbenv/bin``
or that the ``RBENV_ROOT`` environment variable is defined.
