在node.js中生成子进程时出错

const { spawn } = require('child_process');
const child = spawn('node', ['file.js']);

const { spawn } = require('child_process');
const env = Object.assign({}, process.env, { MY_VAR: 'my_value' });
const child = spawn('node', ['file.js'], { env });

child.on('error', (err) => {
  console.error('Error occurred:', err);
});

child.stdout.on('data', (data) => {
  console.log(`Output: ${data}`);
});

child.stderr.on('data', (data) => {
  console.error(`Error output: ${data}`);
});
