标题[问题] pytube RegexMatchError
时间Mon Nov 12 20:33:10 2018
参照网路上的教学试试用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\\')

错误如下

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!

2F：→ s860134: 看了一下那是他写的 pattern 11/13 00:45
甚麽东西XD 不懂
3F：→ s860134: 应该是 youtube 的资料格式有变，他爬失败惹 11/14 00:58
4F：→ s860134: 你先跳过他的范例做别的吧@@ 11/14 00:59
5F：→ dpes10087: pytube ->cipher.py ->get_initial_function_name(js) 11/14 10:53
6F：→ dpes10087: pattern= r'\bc\s*&&\s*d\.set\([^,]+\s*,\s*\([^)]*\) 11/14 10:55
7F：→ dpes10087: \s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\(' 11/14 10:55
8F：→ dpes10087: 再对cipher.py重新编译一次 11/14 10:56
9F：→ dpes10087: 你的Code范例是旧的，很多function都改掉了。 11/14 10:58
谢谢 解决了!
范例好像是旧的 虽然我看的那篇教学文是2017年5月的..
不过後来有找到从PiPy网站看pytube library
里面的function都不太一样了
几乎都是加上了一个streams
像是
yt.streams.filter(only_audio=True).all()
这样
目前可以用python抓youtube影片了
谢谢!!!
