1、初始化一个vue项目/vue init webpack ，可以把多余的文件删除。只保留下面

 

2、修改package.json

{  "name": "ggg-ui",  "description": "A Vue.js project",  "version": "1.1.1",  "author": "guowf <380482989@qq.com>",  "license": "MIT",  "private": false,  "scripts": {    "dev": "cross-env NODE_ENV=development webpack-dev-server --open --hot",    "build": "webpack --display-error-details --config webpack.config.js"  },  "dependencies": {    "vue": "^2.5.11"  },  "browserslist": [    "> 1%",    "last 2 versions",    "not ie <= 8"  ],  "devDependencies": {    "babel-core": "^6.26.0",    "babel-loader": "^7.1.2",    "babel-preset-env": "^1.6.0",    "babel-preset-stage-3": "^6.24.1",    "cross-env": "^5.0.5",    "css-loader": "^0.28.7",    "file-loader": "^1.1.4",    "vue-loader": "^13.0.5",    "vue-template-compiler": "^2.4.4",    "webpack": "^3.6.0",    "webpack-dev-server": "^2.9.1"  },  "main": "/dist/gggUi.js",  "repository": {    "type": "git",    "url": "https://github.com/13714273163/ggg-vue-ui.git"  }}

　3、根目录新建webpack.config.js文件内容如下

var path = require('path')var webpack = require('webpack')module.exports = {  entry: './src/index.js',  output: {    path: path.resolve(__dirname, './dist'),    publicPath: '/dist/',    filename: 'gggUi.js', // 我们可不想打包后叫build.js 多low啊 起一个与项目相对应的    library: 'gggUi', // library指定的就是你使用require时的模块名，这里便是require("PayKeyboard")    libraryTarget: 'umd', //libraryTarget会生成不同umd的代码,可以只是commonjs标准的，也可以是指amd标准的，也可以只是通过script标签引入的。    umdNamedDefine: true // 会对 UMD 的构建过程中的 AMD 模块进行命名。否则就使用匿名的 define。  },  module: {    rules: [{        test: /\.css$/,        use: [          'vue-style-loader',          'css-loader'        ],      }, {        test: /\.vue$/,        loader: 'vue-loader',        options: {          loaders: {}          // other vue-loader options go here        }      },      {        test: /\.js$/,        loader: 'babel-loader',        exclude: /node_modules/      },      {        test: /\.(png|jpg|gif|svg)$/,        loader: 'file-loader',        options: {          name: '[name].[ext]?[hash]'        }      }    ]  },  resolve: {    alias: {      'vue$': 'vue/dist/vue.esm.js'    },    extensions: ['*', '.js', '.vue', '.json']  },  devServer: {    historyApiFallback: true,    noInfo: true,    overlay: true  },  performance: {    hints: false  },  devtool: '#eval-source-map'}if (process.env.NODE_ENV === 'production') {  module.exports.devtool = '#source-map'  // http://vue-loader.vuejs.org/en/workflow/production.html  module.exports.plugins = (module.exports.plugins || []).concat([    new webpack.DefinePlugin({      'process.env': {        NODE_ENV: '"production"'      }    }),    new webpack.optimize.UglifyJsPlugin({      sourceMap: true,      compress: {        warnings: false      }    }),    new webpack.LoaderOptionsPlugin({      minimize: true    })  ])}

4、修改.gitignore文件

切记要把dist加上注释，不然没把dist传上去

5、我的src文件参考

其中index.js是总的文件出口，pachages下面的index是各个文件的出口（也就是element可以一次性导入或者按需导入的做法）

 

5、打包：npm run build /发布：npm publish 

6、在新项目引用试试

main.js

xx.vue

效果图
