vux执行npm run dev 的时候报错 not yet sup ported outside strict mode？

Question

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:\work\nodejsspace\mmrun>npm run dev

mmrun@1.0.0 dev D:\work\nodejsspace\mmrun
node build/dev-server.js

Answer 1

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。

Answer 2

我也是报这个错~~~window系统，好难弄啊。。

Answer 3

啊能贴下你的部分代码？最好大块些？

Answer 4

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

Answer 5

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
