Pytube 仅定期工作(KeyError: 'assets') [英] Pytube only works periodically (KeyError: 'assets')

问题描述

在尝试运行我的小型测试脚本时，Pytube 十次中有五次会向我发送此错误.

Five out of ten times Pytube will send me this error when attempting to run my small testing script.

脚本如下:

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'

我很困惑.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.

I am very confused. I attempted to reinstall Python plus pytube but I can't seem to remedy this issue. It's increasingly perplexing that the script works half of the time, but not the other half.
