具有多个 Angular 路由的循环依赖

Question

我正在使用 Webpack 4.15.1 开发 Angular 6.0.7 应用程序。该应用程序在使用 webpack-dev-server 时运行良好，但是一旦我尝试使用生产模式构建它，它就会在 HtmlWebpackPlugin 发射阶段失败。

它一定与 HtmlWebpackPlugin 有关，因为如果我删除该插件，那么 javascript 文件将毫无问题地生成。可能与生成的块数有关。

直到我向我的应用程序添加两条新路由后才发生这种情况。一旦我删除了 任意两个 路由，应用程序就可以正常编译了。这是错误：

> webpack --config webpack/webpack.production.config.js --progress

我试图创建一个可运行的小示例，但无法重现该问题。这是存储库 when it compiles and when it does not. The relevant commit after which this issue appeared is found here.

感谢您的任何建议。我整天都在调试这个。

Answer 1

问题显然是由 html-webpack-plugin 与 chunksSortMode: 'dependency' 进入某种循环引起的，所以我手动排序如下：

chunks: ['polyfills', 'vendor', 'main'],
chunksSortMode: 'manual'

Answer 2

几天前我遇到了同样的问题。我找到了 3 个可能的修复方法。

重置chunksSortMode

plugins: [
     new HtmlWebpackPlugin({
         chunksSortMode: 'none'
     })
 ]

更新html-webpack-plugin

将 html-webpack-plugin 更新到 v4.0.0 或更新版本，因为 toposort was removed in v4.0.0. In addition, you can check that in the dependencies for v4.0.0

修复循环依赖

安装circular-dependency-plugin
运行没有 html-webpack-plugin
如果可能，尝试修复插件报告的循环依赖关系

我还意识到 mocha-webpack 的最新版本由于 toposort 也有同样的问题，在这种情况下，我唯一的解决方案是降级 webpack@3
