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 react@16.3.0 react-dom@16.3.0 --save
或者
npm i -S react@16.3.0 react-dom@16.3.0
npm安装webpack、webpack-cli等包
npm install webpack@4.4.1 webpack-cli@2.0.13 webpack-dev-server@3.1.1 webpack-merge@4.1.2 babel-cli@6.26.0 babel-preset-env@1.6.1 babel-preset-react@6.24.1 babel-preset-react-hmre@1.1.1 babel-loader@7.1.4 --save-dev
或者
npm i -D webpack@4.4.1 webpack-cli@2.0.13 webpack-dev-server@3.1.1 webpack-merge@4.1.2 babel-cli@6.26.0 babel-preset-env@1.6.1 babel-preset-react@6.24.1 babel-preset-react-hmre@1.1.1 babel-loader@7.1.4
安装 react-router-dom
npm install react-router-dom --save-dev
或者
