使用webpack v2.2时，是否从webpack-dev-server中弃用了“ --content-base”？

Question

我开始迁移webpack 2.2，在配置webpack-dev-server时遇到问题，我的构建脚本是

  "build": "webpack -d && cp src/index.html dist/index.html && webpack-dev-server --content-base src/"

低于错误

ERROR in multi (webpack)-dev-server/client?http://localhost:8080 ./src/app/index.js content-base ./src
Module not found: Error: Can't resolve 'content-base' in 'E:\React\react-basics'
 @ multi (webpack)-dev-server/client?http://localhost:8080 ./src/app/index.js content-base ./src

ERROR in multi (webpack)-dev-server/client?http://localhost:8080 ./src/app/index.js content-base ./src
Module not found: Error: Can't resolve 'E:\React\react-basics\src' in 'E:\React\react-basics'
 @ multi (webpack)-dev-server/client?http://localhost:8080 ./src/app/index.js content-base ./src
webpack: Failed to compile.

好像我在没有内容库的情况下设置脚本正常工作

 "build": "webpack -d && cp src/index.html dist/index.html && webpack-dev-server

为什么会出现此错误，如何为webpack 2.2设置webpack-dev-server？

我建议您在webpack配置文件中配置devServer设置：

范例 ：

  devServer: {
        // All options here: https://webpack.js.org/configuration/dev-server/

        // enable HMR on the server
        hot: true,
        // match the output path
        contentBase: resolve(__dirname, '../dist'),
        // match the output `publicPath`
        publicPath: '/',

        // Enable to integrate with Docker
        //host:"0.0.0.0",

        port: 3000,
        historyApiFallback: true,
        // All the stats options here: https://webpack.js.org/configuration/stats/
        stats: {
            colors: true, // color is life
            chunks: false, // this reduces the amount of stuff I see in my terminal; configure to your needs
            'errors-only': true
        }
    },

你可以从类似的package.json invode的WebPack-dev的服务器在这里 ：

"start": "set NODE_ENV=development && webpack-dev-server --open --config ./webpack/webpack.config.dev.js",
