这是一篇很长的文章，我试图包括所有可能相关的内容。 我的环境是带有Angular 5和webpack的.Net Core 2.0。
我的应用程序在所有内容上都可以完美地进行开发。 我没有问题或任何错误。 但是，当我发布应用程序（生产版本）时，出现了错误。
延迟加载时出现错误。
我认为我的生产配置有些遗漏，或者由于库而发生了一些奇怪的事情。
我在最后写了错误和该部分，我还包括了每个配置文件。

路由样本：
{ path: '', loadChildren: './components/home/home.module#HomeModule' }
直到这部分，当我使用以下命令构建时，一切工作正常：
node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js
node node_modules/webpack/bin/webpack.js
但是当我使用如下的生产版本时：
node node_modules/webpack/bin/webpack.js --config webpack.config.vendor.js --env.prod
node node_modules/webpack/bin/webpack.js --env.prod
当我尝试浏览此编译内容时，它抛出以下错误：
Error: Cannot find module './components/home/home.module.ngfactory'.
