尝试使用pytube时，Tkinter回调出现异常

Question

当尝试使用我制作的视频下载程序时，我不断收到一个错误。我已经看了很多其他问题，试图找到解决方案，但这几乎就像我是唯一一个有这个问题的

附件是错误和我的代码

import pytube
import tkinter
from tkinter import *
from pytube import YouTube

root = Tk()
root.geometry('500x300')
root.resizable(0,0)
root.title("DataFlair-youtube video downloader")


Label(root,text = 'Youtube Video Downloader', font ='arial 20 bold').pack()

link = StringVar()

Label(root, text = 'Paste Link Here:', font = 'arial 15 bold').place(x= 160 , y = 60)
link_enter = Entry(root, width = 70,textvariable = link).place(x = 32, y = 90)


def Downloader():

url =YouTube(str(link.get()))
video = url.streams.first()
video.download()
Label(root, text = 'DOWNLOADED', font = 'arial 15').place(x= 180 , y = 210)  


Button(root,text = 'DOWNLOAD', font = 'arial 15 bold' ,bg = 'pale violet red', padx = 2, command = Downloader).place(x=180 ,y = 150)



root.mainloop()

Answer 1

其他人也面临着与pytube相同的问题。您可能需要在此处查看解决方案。堆栈溢出问题

Answer 2

使用Pytube10.8.3运行时出现错误404，但它与最新的10.8.5一起工作

YouTube有时会对页面进行更改，PyTube可能也需要更新。
