child_process.spawn('cd ../ && pwd') 报错 ENOENT

Question

学习child_process的过程中，有一个小demo

/**

 */

"use strict";

const {spawn,execSync} = require('child_process');
const {resolve} = require('path');
process.chdir(resolve(__dirname, '../'));

function main() {
    // execSync 可以正确执行
    console.log(execSync('cd ../ && pwd').toString());

    // spawn 不能正确执行
    const chp = spawn(`cd ../ && pwd`);
    chp.stdout.on('data', data => {
        console.log(data.toString());
    });
    chp.on('close', () => {
        resolve();
    });
}

main();

execSync执行正确打出log
spawn返回报错

这种写法不对，spawn只能执行一条命令：spawn(command[,args])
例如:spawn("cd", ["../"])
要执行多条命令参考:https://segmentfault.com/q/10...
