FileNotFoundError: [Errno 2] No such file or directory: 'ifconfig'

我开始从一个 udemy 那里学习道德黑客 course.We 被教导如何通过 subprocess.call 的 2 种方法更改 mac 地址，而第一种方法是成功的，但第二种方法是给我的错误，我无法理解 这是我的代码

#! /usr/bin/python3.5
import subprocess
interface = input("Enter Interface of Your Choice: ")
mac_chg = input("Enter New Mac Address: ")
print("[+]Changing Mac ADDRESS of " + interface + " to " + mac_chg)
subprocess.call(["ifconfig", interface, "down"])
subprocess.call(["ifconfig", interface, "hw", "ether", mac_chg])
subprocess.call(["ifconfig", interface, "up"])

这是错误

Traceback (most recent call last):
  File "/home/kali/PycharmProjects/hello/main.py", line 7, in <module>
    subprocess.call(["ifconfig", interface, "down"])
  File "/usr/lib/python3.8/subprocess.py", line 340, in call

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'ifconfig'

Process finished with exit code 1

由于这个错误，我无法进行 提前谢谢你

在 linux 默认情况下，subprocess.call 不使用 shell 到 运行 我们的命令，因此您不能使用 shell 命令，例如 cd .

所以只需在subprocess.call中再添加一个参数即shell= True 然后尝试执行。

例如：

subprocess.call(["ifconfig", interface, "down"], shell=True).
