webpack 安裝后提示CLI

webpack 4X 后需要安裝webpack-cli 請注意需要安裝在同一目錄

npm install --save-dev webpack -g

輸入以上命令后: webpack -v 提示:

The CLI moved into a separate package: webpack-cli
Would you like to install webpack-cli? (That will run npm install -D webpack-cli) (yes/NO)NO
It needs to be installed alongside webpack to use the CLI

這里提示安裝 webpack-cli// 是因為到了webpack4, webpack 已經將 webpack 命令行相關的內容都遷移到 webpack-cli，所以除了 webpack 外，我們還需要安裝 webpack-cli：

//因為上面的webpack是全局安裝的,因此這里我們安裝weback-cli也是需要全局安裝的!
npm install --save-dev webpack-cli -g
