Question

我正在制作一个脚本，该脚本将使用子进程模块来ping IP地址。但是当我尝试运行它时，它说：

Traceback (most recent call last):
  File "C:\Users\YUZi5\OneDrive\Desktop\huetest.py", line 99, in <module>
    subprocess.run("ping", int(hhip), "/dev/null", capture_output=True) #doesnt work rn
ValueError: invalid literal for int() with base 10: '192.168.1.109'

我已经查看了其他一些方法来执行此操作，但是它不起作用。有人可以帮忙吗。完整的代码在这里：

            if ques == ('n'):
                continue

查看if操作==（'6'），以查看我要添加的特定部分。

您需要在subprocess.run方法中将参数作为列表传递。所以你的线

subprocess.run("ping", int(hhip), "/dev/null", capture_output=True)

应更改为

subprocess.run(["ping", hhip, "/dev/null"], capture_output=True)

ip地址更改为整数
