这里是代码:
>>> from pytube import YouTube
>>> v=YouTube('https://www.youtube.com/watch?v=Wl2OyaZVU3U')
>>> v.title
'Maroon 5 - Memories (Lyrics)'
>>> v.streams
<pytube.query.StreamQuery object at 0x7f76859e3a20>
>>> v.download()
Traceback (most recent call last):
File "<pyshell#9>", line 1, in <module>
v.download()
AttributeError: 'YouTube' object has no attribute 'download'
我该如何解决这个问题?
