运行项目是提示`Module build failed: Error: Plugin/Preset files are not allowed to export objects, only functions.`

原来是babel版本兼容问题

修改为

"devDependencies": { 
        "babel-core": "^6.26.0",
        "babel-eslint": "7.2.3",
        "babel-loader": "^7.1.2",
        "babel-plugin-transform-decorators-legacy": "^1.3.4",
        "babel-preset-es2015": "^6.24.1",
        "babel-preset-es2015-loose": "^8.0.0",
        "babel-preset-react": "^6.24.1",
        "babel-preset-stage-1": "^6.24.1",

将高版本的babel配置做降级修改：  
![原本的babelrc][babelrc]

同步降级为：

{ 
      "presets": [
        ["es2015", {  "loose": true }],
        "stage-1",
        "react"
      ],
      "plugins": ["transform-decorators-legacy", "react-hot-loader/babel"]
    }

重新 npm run dev 问题解决
