vue-cli如何打包和图片上传丢失问题

vue项目的打包

需要修改config/index.js里的assetsPublicPath的字段，初始项目是/他是指向项目根目录的也是为什么会出现错误，这时改为./

如下：

 build: {
    // Template for index.html
    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: './',     //加上一个 . 改变路径

    /**
     * Source Maps
     */

    productionSourceMap: true,
    // https://webpack.js.org/configuration/devtool/#production
    devtool: '#source-map',

    // Gzip off by default as many popular static hosts such as
    // Surge or Netlify already gzip all static assets for you.
    // Before setting to `true`, make sure to:
    // npm install --save-dev compression-webpack-plugin
    productionGzip: false,
    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  }

然后在命名行里输出npm run build进行打包，这时你的项目下会出现dist文件夹，复制出来上传服务器

解决vue-cli打包时背景图片丢失问题

需要更改build/utils.js的配置，如下

    if (options.extract) {
      return ExtractTextPlugin.extract({
        publicPath:'../../',
        use: loaders,
        fallback: 'vue-style-loader'
      })
    } else {
      return ['vue-style-loader'].concat(loaders)
    }
