MAC系统，这两天在搞自动化，发现不管我更换什么端口号，比如9421、9422等，拉起微信小程序后，都报端口占用，求各位大佬帮忙解惑，非常感谢！

代码：

import minium

config = {

    "project_path": "/Users/xx/work/test",

    "dev_tool_path": "/Applications/wechatwebdevtools.app/Contents/MacOS/cli",

    "debug_mode": "debug",

    "platform": "ide",

    "app": "wx",

    "test_port": 9421

}

try:

    mini = minium.Minium(config)

    system_info = mini.get_system_info()

    print(system_info)

except Exception as e:

    print(f"执行过程中出现错误: {e}")

错误输出：

[error] {

  code: 10,

  message: 'Error: 错误 Error: Port 9421 is in use (code 10)Error: Port 9421 is in use\n' +
