webpack4.0.1安裝問題和webpack.config.js的配置變化

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：
1、webpack -v 版本號出不來
提示：

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

意思是CLI被移動到了一個專門的包 webpack-cli裏了。
請安裝webpack-cli 的除了webpack自己使用cli
當用npm時，使用npm install webpack-cli -D安裝。
當用yarn時，使用yarn add webpack-cli -D安裝。

解決辦法：全局安裝webpack-cli

npm install webpack-cli -g

 

就能提示出版本號了。
