### 当调试出现问题
1,
```
https://stackoverflow.com/questions/27688804/how-do-i-debug-error-spawn-enoent-on-node-js

const path = require("path");
let { spawn } = require("child_process");
// console.log(123456, process.cwd())
// process.cwd()
let child = spawn("node", ["1.test.js", "a", "b", "c"], {
	cwd: path.join(__dirname, "./")
});

//如果不写stdio 默认是管道类型
child.stderr.on("data", function(data) {
	console.log(data.toString());
});
child.on('exit', function () {
    console.log('exit')
});
child.on('close', function () {
    console.log('close')
})
child.on('error', function (err) {
    console.log('发生错误')
});
