This does not check whether the target actually exists, only judge from the appearance.

If it is, returns the path. If false, check if the path is an archive file (such as a .whl). The function checks if the path is a file. If false, if the path has an @, it will treat it as a PEP 440 URL requirement and return the path. z Directory zC is not installable.
