如何在Python脚本中执行pm2节点js的启动/停止/状态？

import subprocess

def start_pm2_node():
    subprocess.run(['pm2', 'start', 'app.js'])

start_pm2_node()

import subprocess

def stop_pm2_node():
    subprocess.run(['pm2', 'stop', 'app.js'])

stop_pm2_node()

import subprocess

def get_pm2_status():
    result = subprocess.run(['pm2', 'status'], capture_output=True, text=True)
    status_output = result.stdout
    # 解析status_output获取状态信息
    # ...

get_pm2_status()
