当我尝试使用pytube仅下载Youtube视频的音频时，为什么仍会出现错误？

问题描述

我正在尝试使用pytube下载视频的音频，但是我不断收到我不理解的错误。

我的代码是：

from pytube import YouTube
lista_de_videos = ["https://www.youtube.com/watch?v=iYYRH4apXDo"]

for video in lista_de_videos:
    yt = YouTube(video)
    yt.streams.get_audio_only().download('/Users/applemacosx/Downloads')

我一直遇到的错误是：

/Users/applemacosx/PycharmProjects/pythonProject6/venv/bin/python /Users/applemacosx/PycharmProjects/pythonProject6/download.py
Traceback (most recent call last):
  File "/Users/applemacosx/PycharmProjects/pythonProject6/venv/lib/python3.8/site-packages/pytube/extract.py",line 288,in apply_descrambler
    stream_data[key] = [
  File "/Users/applemacosx/PycharmProjects/pythonProject6/venv/lib/python3.8/site-packages/pytube/extract.py",line 290,in <listcomp>
    "url": format_item["url"],KeyError: 'url'

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "/Users/applemacosx/PycharmProjects/pythonProject6/download.py",line 84,in <module>
    yt = YouTube(video)

    self.descramble()
  File "/Users/applemacosx/PycharmProjects/pythonProject6/venv/lib/python3.8/site-packages/pytube/__main__.py",line 132,in descramble
    apply_descrambler(self.player_config_args,fmt)
  File "/Users/applemacosx/PycharmProjects/pythonProject6/venv/lib/python3.8/site-packages/pytube/extract.py",line 300,in apply_descrambler
    cipher_url = [
  File "/Users/applemacosx/PycharmProjects/pythonProject6/venv/lib/python3.8/site-packages/pytube/extract.py",line 301,in <listcomp>
    parse_qs(formats[i]["cipher"]) for i,data in enumerate(formats)
KeyError: 'cipher'

Process finished with exit code 1

有人可以向我解释我做错了吗？

解决方法

keyerror:'cipher'问题早已在pytube存储库中修复。您只需要从存储库链接中重新安装pytube

pip uninstall pytube
pip install git+https://github.com/nficano/pytube

尝试一下：

from pytube import YouTube
yt=YouTube(link)
t=yt.streams.filter(only_audio=True).all()
t[0].download(/path)

参考：-Download audio from YouTube using pytube

您要做的第一件事是：

pip3 uninstall pytube
`pip3 install pytube3`

您也可以尝试pytubex

到处寻找这个。这是我发现的唯一具有解决方案的线程。该问题似乎是由于pytube3文件夹中有两个文件，即extract.py和ciphers.py。您需要更改其中的一些代码。访问 https://github.com/nficano/pytube/issues/641
