尝试使用 pytube 时 Tkinter 回调中的异常

Question

尝试使用我制作的视频下载器时，我不断收到这样的错误提示。我已经看了很多其他问题试图找到解决方案，但几乎就像我是唯一遇到这个问题的人

附上错误和我的代码

   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

当我使用 Pytube 10.8.3 运行时出现错误 404 但它适用于最新的 10.8.5

只是 YouTube 有时会在页面上进行更改，PyTube 可能也需要更新。
