尝试使用 PyTube 和 Tkinter 构建时出现正则表达式错误

Question

我在尝试运行此代码时遇到此错误。我想用 tkinter 和 pytube

构建一个 youtube 视频下载器

pytube.exceptions.RegexMatchError: regex_search: could not find match for (?:v=|\/)([0-9A-Za-z_-]{11}).*

from tkinter import *
from pytube import YouTube

window = Tk()

def downloaderr():
     yt = YouTube(videolink.get())
     yt.streams.first().download()


window.geometry('750x750')
window.title("YouTube Video Downloader")
lbl = Label(window,text="Video Linkini Yapıştırıp Butona Tıklayınız")
lbl.grid(column=5,row=10)
videolink = Entry(window,width=70)
videolink.grid
btn = Button(window,text= "Click to Download",command=downloaderr())
btn.grid(column=15,row=15) 
window.mainloop()

Answer 1

这是因为您在 Button 作业中调用了 downloaderr。

btn = Button(window,text= "Click to Download",command=downloaderr())

应该是

btn = Button(window,text= "Click to Download",command=downloaderr)

但是，当用户按下按钮时，您仍然会收到该错误。错误的原因是 videolink.get() returns 与 pytube 所需的正则表达式模式不匹配。
