按照課程的所使用包和插件的版本號進(jìn)行安裝，如npm i webpack@3.10.0?

到這一節(jié)npm run dev的時候提醒按照 webpack? cli，咋整呢？

azdeMacBook-Pro:vue-ssr az$ npm run dev

> vue-ssr@1.0.0 dev /Users/az/Desktop/vue-ssr

> cross-env NODE_ENV=development webpack-dev-server --config webpack.config.js

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
