我正在用tkinter在pytube中制作Youtube音频下载程序，以便将其放在图形界面中。它在一周前运行，但在我今天运行时不起作用。我不知道该怎么做，这是我希望任何人都能帮助我的代码。我修复了pytube中的密码错误，它删除了这个错误，我不知道这是怎么回事。
python版本：3.8
代码：
import tkinter as tk
from tkinter import filedialog
import os
from pytube import YouTube
root = tk.Tk()
root.title('Youtube to audio converter')
root.iconbitmap('000.ico')
root.geometry('600x400')
text1 = tk.Label(root, text='Youtube to audio converter:', fg="red", font=('TkDefaultFont', 18) ).place(x=150, y=0)
textEntry = tk.Entry(root, width=60)
textEntry.place(x = 120, y = 40)
text2 = tk.Label(root, text='Paste the link to the music video in the box and hit the button: ').place(x=115, y=65)
def download():
link = textEntry.get()
print(link)
yt = YouTube(link)
t = yt.streams.filter(only_audio=True)
t[0].download()
button = tk.Button(root, text='Download', bg='#ff3d3d', font=('TkDefaultFont', 14), command=download).place(x=250, y =100)
text3 = tk.Label(root, text='Do you want it in mp3? If so, put the name in the box below (do not forget to put the extension .mp4) n Remember: if the file is not in the same directory it will not be converted.').place(x=30, y=150)
textEntry2 = tk.Entry(root, width=60)
textEntry2.place(x=120, y=190)
def convert():
archivo=textEntry2.get()
if os.path.isfile(archivo):
os.rename(archivo, archivo + '.mp3')
else:
text4 = tk.Label(root, text='That is not a file or file not found', font=('TkDefaultFont', 14)).place(x=170, y=280)
button2 = tk.Button(root, text='Convert to .mp3', bg='#ff3d3d', font=('TkDefaultFont', 14), command=convert ).place(x=220, y =220)
root.mainloop()
错误：

再次感谢您的帮助！！
我记得读到youtube不断更改其API，以防止您剥离视频的音频。还有一个名为youtube dl的软件包可以进行音频剥离。由于youtube API再次更改，您必须每两周更新一次软件包。这很可能也是你正在经历的。
为了回答您的问题，transform_plan[0]的返回可能发生了变化，或者该值所依赖的任何结构都发生了变化。您应该回溯代码并找到变化点，或者创建回归测试，以便下次轻松找到这些问题。
