vue 运行时报错： Cannot assign to read only property 'exports' of object 'Object'

export和import共用了导致不兼容引起的

npm install babel-plugin-transform-es2015-modules-commonjs

在.babelrc中配置

{
  "presets": [
    ["env", {
      "modules": false
    }],
    "stage-2"
  ],
  "plugins": [
    "transform-es2015-modules-commonjs"
  ]
}
