    playlist.download_all()

警告

播放列表中的视频数量：0个播放列表。py：24：弃用警告：调用已弃用的函数download_all（此函数将将来删除。请通过.videos进行迭代。）

Answer 1

根据一些研究，似乎pytube3 == 9.6.4与YouTube的HTML代码之间存在问题。问题与pytube3如何读取YouTube URL有关。下面的代码通过使用正则表达式解决了这个问题，该正则表达式与YouTube更新的HTML代码匹配。

import re
from pytube import Playlist

playlist = Playlist("https://www.youtube.com/playlist?list=PL6gx4Cwl9DGCkg2uj3PxUWhMDuTw3VKjM")
playlist._video_regex = re.compile(r"\"url\":\"(/watch\?v=[\w-]*)")
print('Number of videos in playlist: %s' % len(playlist.video_urls))
for url in playlist.video_urls:
   print(url)
   
   ###############################
   OUTPUT
   ###############################
   Number of videos in playlist: 23

我确实注意到pytube3当前不受支持，有人将其分叉到pytubeX。我正在尝试找出下载内容，因为我无法使该作品与pytube3或pytubex一起使用。我将继续研究这个问题。

如何使用pytube下载youtube播放列表视频？
