2. new webpack.optimize.OccurenceOrderPlugin(),错误

https://github.com/webpack/webpack/issues/1964

用new webpack.optimize.OccurrenceOrderPlugin()替代 ，似乎是webpack2.0的问题

3. Error: Can't resolve 'react-hot-loader/patch

用npm install react-hot-loader@next --save 更新react-hot-loader

explain: 原贴被删除，这边用的快照打开的

@ddydeveloper You had "^1.3.1" in your package.json. This gets an old version of react-hot-loader (V1) instead of V3. React Hot Loader V1 is now deprecated and is expected to break. The most current version of React Hot Loader is V3, and is on the next branch. Its the one you should be using. If you install React Hot Loader via npm install react-hot-loader it will get the deprecated version instead of the newest one. npm install react-hot-loader@next is the command that should be ran with this library until V3 becomesmaster branch. Likely yarn changed your version of React Hot Loader - which is why it was working a while ago. Deleting node-modules removes any potential overwrites and reinstalling gets you the latest version.

4. 最后一个warning

new webpack.NoErrorsPlugin()

用 new webpack.NoEmitOnErrorsPlugin() 替代上面一句话，这里可以直接根据虚拟台的提示修改
