vue 在部署不工作时路由延迟加载

Question

像这样在我的路由中实现延迟加载后：

component: () => import('./pages/home/index/index.vue')

在本地它有点工作（在某些路线上丢失字体）。

当代码由 CI/CD 环境部署时，任何设置为延迟加载的路由都不会在浏览器中加载，并出现此控制台错误：

Uncaught SyntaxError: Unexpected token <

检查问题后，它指向 <head> 标签，里面我有这个：

<link href=/dist/static/css/app.4d19fef0c231f16b8783490b2895fe94.css rel=stylesheet><link href=/dist/static/css/app.1fa1a352ec9d24165aab94b33bba4db2.css rel=stylesheet>

在最终捆绑包中拆分 css 个文件。

所以这说明我可能没有在 webpack 配置中很好地配置一些东西？

感谢您的帮助。

webpack 配置是标准的 vue-cli 配置（这是产品配置）：

var path = require('path')
var utils = require('./utils')
var webpack = require('webpack')
var config = require('../config')
var merge = require('webpack-merge')
var baseWebpackConfig = require('./webpack.base.conf')
var CopyWebpackPlugin = require('copy-webpack-plugin')
var HtmlWebpackPlugin = require('html-webpack-plugin')
var ExtractTextPlugin = require('extract-text-webpack-plugin')
var OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')

var env = config.build.env

var webpackConfig = merge(baseWebpackConfig, {
  // The following line must be used for production because of the 
  // folder structure we have in the packaged app.  
  //context: __dirname + "/../../app",

  module: {
    rules: utils.styleLoaders({
      sourceMap: config.build.productionSourceMap,
      extract: true
    })
  },
  devtool: config.build.productionSourceMap ? '#source-map' : false,
  output: {
    path: config.build.assetsRoot,
    filename: utils.assetsPath('js/[name].[chunkhash].js'),
    chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
  },
  plugins: [
    // http://vuejs.github.io/vue-loader/en/workflow/production.html
    new webpack.DefinePlugin({
      'process.env': env
    }),
    new webpack.optimize.UglifyJsPlugin({
     // Eliminate comments
        comments: false,

    // Compression specific options
       compress: {
         // remove warnings
            warnings: false,

         // Drop console statements
            drop_console: true
       },
    }),
    // extract css into its own file
    new ExtractTextPlugin({
      filename: utils.assetsPath('css/[name].[contenthash].css')
    }),
    // Compress extracted CSS. We are using this plugin so that possible
    // duplicated CSS from different components can be deduped.
    new OptimizeCSSPlugin(),
    // generate dist index.html with correct asset hash for caching.
    // you can customize output by editing /index.html
    // see https://github.com/ampedandwired/html-webpack-plugin
    new HtmlWebpackPlugin({
      filename: config.build.index,
      template: 'index.html',
      inject: true,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeAttributeQuotes: true
        // more options:
        // https://github.com/kangax/html-minifier#options-quick-reference
      },
      // necessary to consistently work with multiple chunks via CommonsChunkPlugin
      chunksSortMode: 'dependency'
    }),
    // split vendor js into its own file
    new webpack.optimize.CommonsChunkPlugin({
      name: 'vendor',
      minChunks: function (module, count) {
        // any required modules inside node_modules are extracted to vendor
        return (
          module.resource &&
          /\.js$/.test(module.resource) &&
          module.resource.indexOf(
            path.join(__dirname, '../node_modules')
          ) === 0
        )
      }
    }),
    // extract webpack runtime and module manifest to its own file in order to
    // prevent vendor hash from being updated whenever app bundle is updated
    new webpack.optimize.CommonsChunkPlugin({
      name: 'manifest',
      chunks: ['vendor']
    }),
    // copy custom static assets
    new CopyWebpackPlugin([
      {
        from: path.resolve(__dirname, '../static'),
        to: config.build.assetsSubDirectory,
        ignore: ['.*']
      }
    ])
  ]
})

if (config.build.productionGzip) {
  var CompressionWebpackPlugin = require('compression-webpack-plugin')

  webpackConfig.plugins.push(
    new CompressionWebpackPlugin({
      asset: '[path].gz[query]',
      algorithm: 'gzip',
      test: new RegExp(
        '\.(' +
        config.build.productionGzipExtensions.join('|') +
        ')$'
      ),
      threshold: 10240,
      minRatio: 0.8
    })
  )
}

if (config.build.bundleAnalyzerReport) {
  var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
  webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}

module.exports = webpackConfig

构建产品设置：

 build: {
    env: require('./prod.env'),
    index: path.resolve(__dirname, '../index.html'),
//    index: path.resolve(__dirname, '../dist/index.html'),
    assetsRoot: path.resolve(__dirname, '../dist'),
//    assetsSubDirectory: '/static',
    assetsSubDirectory: 'static',
//    assetsPublicPath: '/app/dist/',
   assetsPublicPath: '/',
    // assetsPublicPath: '/dist/',
    fontPath: '/static',
    productionSourceMap: true,
    // 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
  },

Answer 1

因为您提到您正在使用 Vue Router 作为您的应用程序。

将 base: '/sub-directory/ 添加到您的路由器代码中。

例如：

export default new Router({
  base: '/foo-bar/',
  routes
})

另外记得在你的 webpack 配置文件中设置你的 public assets 路径让 /sub-directory/

Answer 2

最后我解决了将 assetsPublicPath: '/dist', 修改为 assetsPublicPath: '/dist/', 的问题。

主要问题是我的树结构应该是 dist/static/... 而对于块文件来说是 diststatic/...

希望这对某人有所帮助。
