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 install webpack-cli -D -> When using yarn: yarn add webpack-cli -D

webpack4.0.1安裝問題，提示：

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 install webpack-cli -D

-> When using yarn: yarn add webpack-cli -D

解決方案：

一、webpack -v 版本號出不來

提示：

二、在項目目錄下要本地安裝webpack-cli -D

npm install webpack-cli -D

三、在項目目錄下要本地安裝webpack

npm install webpack -D

四、必須使用配置文件：webpack.config.js

不要使用webpack命令，如：webpack demo01.js bundle01.js，不能再執行了。

五、webpack.config.js文件的變化

webpack.config.js裏的配置，不再支持 module下的loaders，需要把loaders改成rules。

即如下：

module: { rules: [ //針對css文件，進行對應的loader處理 { test: /\.css$/, loader: "style-loader!css-loader" } ] }
