Angular 7：延迟加载WebWorkers导致ng服务在首次重新加载时崩溃

Question

我试图使用worker-plugin和Comlink在Angular 7中延迟加载包含WebWorkers的模块。基本上，我已经按照here的教程进行编译并且工作正常。

当运行ng serve时，它会在第一次使用TypeError: Cannot read property 'kind' of undefined重新加载时崩溃。

代码在GitHub上。 https://github.com/jetkiwi/angular-comlink-lazyload-example

更新我的同事发现使用--aot选项运行可以防止它崩溃。

将@ angular-devkit / build-angular更新为0.13.8解决了这个问题。

我假设它与@ ngtools / webpack有关。 https://github.com/angular/angular-cli/releases/tag/v7.3.8
