Nodejs里运行npm run dev shell脚本无效果？

Question

问题描述
Nodejs里如何运行npmrundevshell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，npmrunscript一个node脚本文件，但是我想在这个脚本文件里运行其它的npmrun，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
varexec=require('child_process').execSyncexec('npmrundev')
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

Answer 1

这就是你想要的varspawn=require('child_process').spawn;spawn('npm',['run','dev'],{stdio:'inherit'});或varexec=require('child_process').execSync;exec('npmrundev',{stdio:'inherit'});
