Brett Cannon added the comment: I found the problem: you have a bug in your code at line 45 (the first line of WolfPathFinder.find_spec()). When you try and import a top-level package the path will always be None since __path__ doesn't exist for a top-level package. You only end up with a `pat

Brett Cannon added the comment: I'm at work and so I don't have access to tar on this machine ATM, so I can't look at your code example. But sys.meta_path might be one level above what you want; you might be looking for sys.path_hooks since https://docs.python.org/3/library/importlib.html#impo
