Demo example broken (KeyError: 'url_encoded_fmt_stream_map')

[jangroth]

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):
  File "<stdin>", line 1, in <module>

KeyError: 'url_encoded_fmt_stream_map'

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 KeyError: 'url_encoded_fmt_stream_map' #467 .
• If this is not acceptable, pytube might not be right for you. pytube3 (see below) could be an option.

I have applied the diffs in pull request #467.

Works fine for me:

Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) [MSC v.1916 32 bit (Intel)] on win32

Apply the diffs from swiftyy-mage's pull request . It should work. Let me know. I'll help.

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[dev-packages]

[packages]
boto3 = "*"
requests = "*"
pytube3 = "*"

[requires]
python_version = "3.7"

I've now switched to pytube3. Works like a charm.
