[問題] pytube RegexMatchError

[wavek (壞貓咪)]

參照網路上的教學試試用pytube庫下載影片

不過開頭就出問題惹QQ


使用的系統為win7 64位元

IDE為PyCharm 並且連接到Anaconda 3 (python 3.7)

Pytube為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看到幾個人有類似問題

不過都沒有解答

所以來這邊求助熱心的高手!

→ s860134: 把你的　pattern 貼101檢查吧 https://regex101.com/
→ s860134: 看了一下那是他寫的　pattern
甚麼東西XD 不懂
→ s860134: 應該是　youtube 的資料格式有變，他爬失敗惹
→ s860134: 你先跳過他的範例做別的吧@@
→ dpes10087: pytube ->cipher.py ->get_initial_function_name(js)
→ dpes10087: pattern= r'\bc\s*&&\s*d\.set\([^,]+\s*,\s*\([^)]*\)
→ dpes10087: \s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\('
→ dpes10087: 再對cipher.py重新編譯一次
→ dpes10087: 你的Code範例是舊的，很多function都改掉了。
謝謝 解決了!
範例好像是舊的 雖然我看的那篇教學文是2017年5月的..
不過後來有找到從PiPy網站看pytube library
裡面的function都不太一樣了
幾乎都是加上了一個streams
像是
yt.streams.filter(only_audio=True).all()
這樣

目前可以用python抓youtube影片了
謝謝!!!
