Tkinter在使用os模块输入cmd命令后没有响应

import tkinter as tk
from tkinter import messagebox
import os
import threading

def run_command_in_thread(command):
    result = os.popen(command).read()
    messagebox.showinfo("命令输出", result)

def on_button_click():
    command = "dir"  # 示例命令
    thread = threading.Thread(target=run_command_in_thread, args=(command,))
    thread.start()

root = tk.Tk()
button = tk.Button(root, text="执行命令", command=on_button_click)
button.pack()
root.mainloop()

import tkinter as tk
from tkinter import messagebox
import os
import asyncio

async def run_command_async(command):
    result = await asyncio.to_thread(os.popen, command).read()
    messagebox.showinfo("命令输出", result)

def on_button_click():
    command = "dir"  # 示例命令
    asyncio.create_task(run_command_async(command))

root = tk.Tk()
button = tk.Button(root, text="执行命令", command=on_button_click)
button.pack()
root.mainloop()
