webpack4.X? react-router

环境准备工作：windows7、webStorm 2017.1.4、Nodejs 8.7.0、npm 5.4.2

PS:安装的时我们都带上版本，这样即便webpack版本发生变化，也不会出现版本问题。

初始化package.json文件
npm init

npm安装react、react-dom包

npm install [email?protected] [email?protected] --save

或者

npm i -S [email?protected] [email?protected]

npm安装webpack、webpack-cli等包

npm install [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] --save-dev

或者

npm i -D [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected] [email?protected]

安装 react-router-dom

npm install react-router-dom --save-dev

或者

npm i -S react-router-dom
