安装了react-redux后，npm start报下面错误
Failed to compile.
./node_modules/_react-redux@7.2.0@react-redux/es/connect/mapDispatchToProps.js Module not found: Can't resolve 'redux' in 'E:\***\node_modules\_react-redux@7.2.0@react-redux\es\connect'
解决如下：
react-redux插件是基于redux的，必须先安装redux先再使用react-redux
npm install –save redux
