我正在尝试使用 PyTube 包下载 youtube 视频，但我无法这样做。我正在使用 Python 3.5 和 pytube 9.2.2。Urllib 在其他程序中没有给我错误，但在这里给我错误。

我正在使用的代码是：

#importing the module
from pytube import YouTube

#where to save
SAVE_PATH = "E:/" #to_do

#link of the video to be downloaded
link="https://www.youtube.com/watch?v=xWOoBJUqlbI"


yt = YouTube(link)


#filters out all the files with "mp4" extension
mp4files = yt.filter('mp4')

yt.set_filename('GeeksforGeeks Video') #to set the name of the file

#get the video with the extension and resolution passed in the get() function
d_video = yt.get(mp4files[-1].extension,mp4files[-1].resolution)
try:
    #downloading the video
    d_video.download(SAVE_PATH)
except:
    print("Some Error!")
print('Task Completed!')

我得到的错误是：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我希望有人能帮助我。PS - 我只是使用 urllib、http 包的初学者。请不要写苛刻的评论，谢谢：0
