Cheesemacfly：

此问题与react-hot-loader程序包有关。您使用的旧版本依赖于ReactMount.js文件node_modules/react/lib夹中存在的文件。

对此没有一种简单的解决方法，但是您可以选择以下几种方法：

Try to follow the instructions here: https://github.com/gaearon/react-hot-loader/blob/v3.0.0-beta.6/docs/README.md#usage-with-external-react (but I have been unlucky so far)
Remove the hot reloader for react (in your webpack.config remove the 'react-hot' loader)
Update the react-hot-loader package to version 3 (here is how to do so: https://github.com/gaearon/redux-devtools/commit/64f58b7010a1b2a71ad16716eb37ac1031f93915). But note that this package has been in alpha for a while now...
Rollback your react version to one that includes the ReactMount.js in the lib folder (15.0.1 used to have this file not sure when it stopped).
