webpack 安装后提示CLI

webpack 4X 后需要安装webpack-cli 请注意需要安装在同一目录

npm install --save-dev webpack -g

输入以上命令后: 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

这里提示安装 webpack-cli// 是因为到了webpack4, webpack 已经将 webpack 命令行相关的内容都迁移到 webpack-cli，所以除了 webpack 外，我们还需要安装 webpack-cli：

//因为上面的webpack是全局安装的,因此这里我们安装weback-cli也是需要全局安装的!
npm install --save-dev webpack-cli -g
