build 处理统一js路径

一般情况下，通过webpack+vuecli默认打包的css、js等资源，路径都是绝对的。

但当部署到带有文件夹的项目中，这种绝对路径就会出现问题，因为把配置的static文件夹当成了根路径，那么要解决这种问题，就得引用相对路径。

解决方式将config下的index.js 修改处理js的统一路径

build: {

    // Template for index.html

    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths

    assetsRoot: path.resolve(__dirname, '../dist'),

    assetsSubDirectory: 'static',

// assetsPublicPath: 'https://sign-web.oss-cn-hangzhou.aliyuncs.com/',

    assetsPublicPath: './',

    /**

    * Source Maps

    */

    productionSourceMap: false,

    // 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

  }
