If the pyenv virtualenv plugin is installed using the [pyenv-installer][1] app script or directly via a [Git clone][2], then the pyenv-virtualenv-init executable, that the `pyenv virtualenv-init` command uses, will not exist in the user's PATH and therefore cannot be found using `$commands[pyenv-virtualenv-init]`. Installing the pyenv-virtualenv plugin in this manner is common among Linux users. Using the pyenv `commands` command, which lists all commands pyenv can run, we can find if the virtualenv-init command is available to pyenv and subsequently the virtualenv plugin, without relying on pyenv-virtualenv-init to exist in the user's PATH.
