"use strict";

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

function main() {
    // execSync 可以正確執(zhí)行
    console.log(execSync('cd ../ && pwd').toString());

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

main();

execSync執(zhí)行正確打出log
spawn返回報錯
