ReadMd啊

命令行参数

cross-env

cross-env MOCK=1 webpack-dev-server --open --config webpack/webpack.dev.js

在webpack配置文件中读取：

const { MOCK } = process.env;

clean-webpack-plugin is outside of the project root. skipping

   new CleanWebpackPlugin(['dist'], {
      root: process.cwd(),
    })

IE11报SecurityError问

解决方案为 Internet选项->安全->本地Internet->站点，把所有勾选取消

devServer 不支持IE了
