python - Pytube 只能定期工作(KeyError : 'assets' )

Question

尝试运行我的小测试脚本时，十次有五次 Pytube 会向我发送此错误。
这是脚本:

import pytube
import urllib.request


from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=3NCyD3XoJgM')

print('Youtube video title is: ' + yt.title + '! Downloading now!')

这是我得到的:

Traceback (most recent call last):
  File "youtube.py", line 6, in <module>
    yt = YouTube('https://www.youtube.com/watch?v=3NCyD3XoJgM')
  File "C:\Users\test\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pytube\__main__.py", line 91, in __init__
    self.prefetch()
  File "C:\Users\test\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pytube\__main__.py", line 183, in prefetch
    self.js_url = extract.js_url(self.watch_html)
  File "C:\Users\test\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\pytube\extract.py", line 143, in js_url
    base_js = get_ytplayer_config(html)["assets"]["js"]
KeyError: 'assets'

我很困扰。我尝试重新安装 Python 和 pytube，但似乎无法解决此问题。越来越令人困惑的是，该脚本有一半时间有效，而另一半时间无效。

如果其他人收到此错误或问题，请在终端或 cmd 中运行此命令:python -m pip install git+https://github.com/nficano/pytube尚未随 pip 安装发布的 pytubeX 更新。 GitHub 链接是解释情况的当前开发人员。
