我是es6的新手。我阅读了一篇博客《ES6开发环境入门指南》。我一步一步地完成了整个过程。然后是安装webpack开发服务器的步骤。然后我将此代码写入cmd-npm run build。我得到这个错误：
λ npm run build
-> jj@1.0.0 build C:UsersgalibDesktopjj
-> webpack-dev-server
The CLI moved into a separate package: webpack-cli
Please install 'webpack-cli' in addition to webpack itself to use the CLI
-> When using npm: npm i -D webpack-cli
-> When using yarn: yarn add -D webpack-cli

您读到的这篇文章可能是在Webpack的cli移动到webpack-cli之前写的，因此您可能需要一个额外的小步骤。
要使用cli，请在安装webpack本身的同时安装"webpack cli"->使用npm时：npm i-D webpack cli->使用yarn时：yarn add-D webpack cli
运行npm i -D webpack-cli，然后可以使用Webpack CLI。
