参照网络上的教学试试用pytube库下载影片
不过开头就出问题惹QQ
使用的系统为win7 64位元
IDE为PyCharm 并且连接到Anaconda 3 (python 3.7)
Pytube为9.3.51版本
我的Code如下
===
from pytube import YouTube
link = "https://www.youtube.com/watch?v=Ik-RsDGPI5Y"
yt = YouTube(link)
print(yt.get_videos())
print(yt.filename)
yt.set_filename('Dancing')
print(yt.filter('flv'))
print(yt.filter('mp4')[-1])
print(yt.filter(resolution='480p'))
video = yt.get('mp4','720p')
video.download('E:\\_sublime\\scrapy\\hey\\')

有在GitHub跟STACK OVERFLOW看到几个人有类似问题
不过都没有解答
所以来这边求助热心的高手!

把你的　pattern 贴101检查吧 https://regex101.com/看了一下那是他写的　pattern

pytube ->cipher.py ->get_initial_function_name(js)pattern= r'\bc\s*&&\s*d\.set\([^,]+\s*,\s*\([^)]*\)\s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\('再对cipher.py重新编译一次你的Code范例是旧的，很多function都改掉了。
