vue-cli的使用

1、vue-cli初始运行项目报错

安装vue-cli：直接npm i vue-cli -g，然后直接vue init webpack projectname，然后进入目录，npm run dev即可，如果报错：Module build failed: Error: "extract-text-webpack-plugin" loader is used without the corresponding plugin, refer to https://github.com/webpack/extract-text-webpack-plugin for the usage example，解决方法如下：

在 webpack.dev.conf.js 中添加 extract-text-webpack-plugin 配置如下

const ExtractTextPlugin = require('extract-text-webpack-plugin')

........


plugins: [
    .............
    // extract css into its own file
    new ExtractTextPlugin({
      filename: utils.assetsPath('css/[name].[contenthash].css'),
      // set the following option to `true` if you want to extract CSS from
      // codesplit chunks into this main css file as well.
      // This will result in *all* of your app's CSS being loaded upfront.
      allChunks: false,
    }),
]
