尝试 ping google.com 时的多次回溯(最近一次调用最后一次)和 FIleNotFoundError

Multiple Traceback (most recent call last) and FIleNotFoundError when trying to ping google.com

我正在尝试编写一个用于 ping ip 地址等的程序。但是每次我尝试 ping 一个 IP 地址时,我总是会遇到多个错误。我尝试了多种不同的方法来 ping 一个 IP 地址,但没有一种方法有效。任何帮助将不胜感激! :D

我的代码:

import time
import socket
import os
import subprocess

time.sleep(1)

print('    _  __        __')
time.sleep(0.3)
print('  / |/ /__  ___/ /__')
time.sleep(0.3)
print(' /    / _ \/ _  / -_)')
time.sleep(0.3)
print('/_/|_/\___/\_,_/\__/')

print('\n\n')

time.sleep(1)

while True:
    prompt = input('>>> ')

    if prompt == '/ip-?':
        print(socket.gethostbyname(socket.getfqdn()))
    elif prompt == '/hn-?':
        print(socket.gethostname())
    elif prompt == '/h':
        print('\n/ip-? --- IP ADDRESS')
        print('/hn-? --- HOST NAME')
        print('/e --- EXIT')
        print('\n')
    elif prompt == '/ip->':
        #THIS IS WHERE THE PROBLEM IS OCCURING
        out = subprocess.run(['ping', 'google.com'], capture_output=True)
        print(out.stdout.decode())
    elif prompt == '/e':
        break

回溯:

Traceback (most recent call last):
  File "D:\PYTHON\PROJECTS\everything.py", line 33, in <module>
    out = subprocess.run(['ping', 'google.com'], capture_output=True)

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

ping.exe应该在系统目录下C:\WindowsSystem32。如果没有路径 运行 失败,请添加它。您可以使用正斜杠来避免 python 使用 \ 转义特殊字符的潜在问题。

out = subprocess.run(['C:/Windows/System32/ping', 'google.com'], capture_output=True)

请注意,这会使您的程序仅 windows。 Linux/Mac 也有“ping”程序,所以如果简单的“ping”不起作用,您可以将其用作后备。 “ping”程序可能有不同的参数和输出,具体取决于平台,因此您可能需要先检查平台版本,并实现两个不同版本的代码。
