问题描述
Nodejs里如何运行npm run dev shell脚本?
问题出现的环境背景及自己尝试过哪些方法
1、在webpack构建的模块里,npm run script一个node脚本文件,但是我想在这个脚本文件里运行其它的npm run,尝试了require('child_process').exec但是无效,执行到这里什么反应都没。
相关代码
var exec = require('child_process').execSync
exec('npm run dev')
你期待的结果是什么?实际看到的错误信息又是什么?
或者在node脚本js文件里如何才能正确执行package.json里的script呢?
补充贴上package.json内容
