在执行npm run dev 时报严格模式的错误,如果去掉文件里面的'strict'标签就可以,但是要改的文件太多了,肯定不是这么解决,各位大神帮我看看。谢谢

D:worknodejsspacemmrun>npm run dev

mmrun@1.0.0 dev D:worknodejsspacemmrun
node build/dev-server.js

将node升级到最新版本 应该是 6.9.5
或者在webpack中不要使用es6语法。
4.x对es6的支持需要开启harmony或者在文件头部加上use strict

dev-server.js 就是检查node和npm版本的工具,应该确实就是版本的问题

配置文件中使用了 ES6 语法,升级你的 NodeJs 版本到 6.x 以上即可解决。

啊能贴下你的部分代码?最好大块些?

我也是报这个错~~~window系统,好难弄啊。。
