Demo example broken (KeyError: 'url_encoded_fmt_stream_map')

I’ve noticed this error since yesterday (used to work, failed from one minute to the next).

I’m new to pytube, but I believe this is related to issue #467 which also shows some recent activity.

Feel free to mark this as a duplicate, just wanted to create a new issue to point out that the actual demo from the 101 documentation stopped working.

>>> from pytube import YouTube
>>> YouTube('https://youtu.be/9bZkp7q19f0').streams.first().download()
Traceback (most recent call last):

UPDATE: The pytube project appears unmaintained at the moment. See here.

• If you are looking to fix the problem mentioned in this issue and are happy to patch source code, follow the advice given in #467 .
• If this is not acceptable, pytube might not be right for you. pytube3 (see below) could be an option.
