Angular 4页面重新加载或重定向抛出“loadChunkError”：true

Question

我正在使用带有webpack构建的angular 6 MVC应用程序。它会在页面加载或重定向时随机抛出“loadChunkError”：true“，错误发生后，角度路由不起作用并连续抛出控制台错误。

[注意：一旦我清除浏览器缓存然后路由工作正常]

Webpack文件

const webpack = require("webpack");

const path = require("path");

const UglifyJsPlugin = require("uglifyjs-webpack-plugin");
const HtmlWebpackPlugin = require('html-webpack-plugin');
var SourceMapDevToolPlugin = require('webpack/lib/SourceMapDevToolPlugin');
let SharedCache = {};
const entryPath = path.resolve(__dirname, "src");
const viewPath = path.resolve(
    __dirname,
    "../Views/Home"
);

const { BaseHrefWebpackPlugin } = require('base-href-webpack-plugin');
const ROOT = path.resolve(__dirname, '');

const app = ${entryPath}; module.exports = envOptions => {envOptions = envOptions || {};

const config = {
    entry: {
        polyfills: `${entryPath}\\polyfills.ts`,
        vendors: `${entryPath}\\vendor.ts`,
        app: `${entryPath}\\main.ts`
    },
    output: {
        path: viewPath,
        publicPath: '/',
        filename: "../../angularBundle/[name].js",
        chunkFilename: '../../angularBundle/[name].js',
        sourceMapFilename: "../../angularBundle/[name].js.map",
    },
    resolve: {
        extensions: [".ts", ".js", ".html"],
        alias: {
            jquery: "jquery/src/jquery"
        }
    },  
module: {
  rules: [
    {
      test: /\.ts$/,
      loaders: ["awesome-typescript-loader?configFileName=./src/tsconfig.json", "angular2-template-loader"]
      },
      {
          test: /\.(ts|js)$/,
          loaders: [
              'angular-router-loader'
          ]
      },
    {
      test: /\.html$/,
      loader: "raw-loader"
    },
    {
      test: /\.css$/,
      loader: "raw-loader"
      }
      ,
      {
          test: /\.(png|jpg|eot|cur|svg|gif|ttf|woff|otf)$/,
          loader: "file-loader",
          options: {
              outputPath: 'fonts/'
          }
      } 
  ]
    },
    devtool: 'eval',
    plugins: [
  new webpack.NoEmitOnErrorsPlugin(),
    new HtmlWebpackPlugin({
        template: viewPath + "/loader.cshtml",
        filename: viewPath + "/Index.cshtml",
        inject: false
        })
    ],
  optimization: {
      splitChunks: { chunks: 'all' },
    },
 };

if (envOptions.MODE === "prod") {
    config.plugins.push(
        new UglifyJsPlugin()
    );
  }

 return config;
};       

错误

错误：未捕获（在承诺中）：对象：{“loadChunkError”：true，“details”：{“type”：“missing”，“request”}

请提供解决问题的解决方案或步骤。

谢谢，Vivek

Answer 1

根本原因：在我的情况下，由于旧的缓存的js块，存在加载块错误。 修复：通过哈希的帮助生成唯一的js修复了问题

[hash]是“为每个构建生成的唯一哈希”

现有

output: {
        path: viewPath,
        publicPath: '/',
        filename: "../../angularBundle/[name].js",
        chunkFilename: '../../angularBundle/[name].js',
        sourceMapFilename: "../../angularBundle/[name].js.map",
    }

更新[已修复问题]

output: {
        path: viewPath,
        publicPath: '/',
        filename: "../../angularBundle/[name].[hash].js",
        chunkFilename: '../../angularBundle/[name].[hash].js',
        sourceMapFilename: "../../angularBundle/[name].[hash].js.map",
    }

Answer 2

• 第1步：使用component而不是loadChildren直接加载组件然后你可以看到实际的错误
• 第2步：修复错误。
• 第3步：像以前一样懒惰地加载组件。
