JavaScript等待child_process派生的python脚本运行

const { spawn } = require('child_process');

// 派生python子进程
const pythonProcess = spawn('python', ['your_script.py']);

// 监听子进程的输出
pythonProcess.stdout.on('data', (data) => {
  console.log(`输出：${data}`);
});

// 监听子进程的错误输出
pythonProcess.stderr.on('data', (data) => {
  console.error(`错误输出：${data}`);
});

// 监听子进程的退出事件
pythonProcess.on('close', (code) => {
  console.log(`子进程退出，退出码：${code}`);
});

const { spawn } = require('child_process');

function runPythonScript(scriptPath, args) {
  return new Promise((resolve, reject) => {
    const pythonProcess = spawn('python', [scriptPath, ...args]);

    let output = '';
    let errorOutput = '';

    pythonProcess.stdout.on('data', (data) => {
      output += data;
    });

    pythonProcess.stderr.on('data', (data) => {
      errorOutput += data;
    });

    pythonProcess.on('close', (code) => {
      if (code === 0) {
        resolve(output);
      } else {
        reject(new Error(`Python脚本运行出错：${errorOutput}`));
      }
    });
  });
}

// 使用示例
runPythonScript('your_script.py', ['arg1', 'arg2'])
  .then((output) => {
    console.log(`脚本运行结果：${output}`);
  })
  .catch((error) => {
    console.error(`脚本运行出错：${error}`);
  });
