问题

我使用 Next.js 开发一个项目，并通过 pm2 运行它：`pm2 start npm -- start`

我可以看到一个名为 `<processName>.out.log` 的文件，但里面没有任何内容。

```jsx
export function getServerSideProps (ctx) {
  console.log('-------test----------')
  return {
    props: {}
  }
}

如何在不费力的情况下获取日志？

I use Next.js to develop a project, and run it by pm2: `pm2 start npm -- start`

I can see a file named `&lt;processName&gt;.out.log`，but that has no content in it.

export function getServerSideProps (ctx) {
console.log('-------test----------')
return {
props: {}
}
}

How can I get logs without much efforts?

var exec = require('child_process').spawn

exec(
'npm',
['run', 'start'],
