package.js
中对于babel的包如下：
"babel-core": "^6.0.0",
"babel-loader": "^6.0.0",
"babel-plugin-transform-object-rest-spread": "^6.26.0",
"babel-plugin-transform-runtime": "^6.0.0",
"babel-plugin-transform-vue-jsx": "^3.5.0",
"babel-preset-es2015": "^6.0.0",
"babel-preset-stage-3": "^6.24.1",
"babel-register": "^6.0.0",
"babel-runtime": "^6.23.0",
"webpack": "^3.6.0",

Vue2.x中的mutation.js文件编译出错

解决方案：
1.确保不要用babel.config.js而是应用.babelrc
2.wepback.base.conf.js中js相干配置如下：
{
test: /.js$/,
loader: "babel-loader",
include: [resolve("src"), resolve("test"), resolve("node_modules/webpack-dev-server/client")]
},

  1. .babelrc文件内容如下：

{
"presets": [

[  "stage-3"

]
],
"plugins": [

"transform-runtime"

]
}
4.留神，肯定不要将es2015加到presets中~~ ~~
