故障排除“未加载运行时编译器"； [英] Trouble shoot "Runtime compiler is not loaded"

问题描述

使用--prod标志构建Angular2应用后，出现以下运行时错误:

I am getting the following runtime error after building my Angular2 app with the --prod flag:

运行时编译器未加载

Runtime compiler is not loaded

我了解生产版本使用AoT，并且在这种情况下不支持运行时编译.
我的问题是:我不知道自己正在做的任何事情都需要运行时编译器.甚至可能是我正在使用的外部组件.

I understand that the production builds use AoT and that runtime compiling isn't supported in this scenario.
My problem is: I am not aware of anything I am doing that would need the runtime compiler. It might even be an external component I am using.

我如何找出导致此错误的组件?

How do I find out what component is causing this error?

推荐答案

当我尝试使用模块类型而不是路径来使用惰性模块加载时，AoT编译也遇到了类似的问题.

I have had the similar issue with AoT compilation when I was trying to use lazy module loading using module type instead of the path.

正确加载:

{ path: 'lazy', loadChildren: 'lazy/lazy.module#LazyModule' }

我已经做到了(崩溃了AoT):

Way, I've done it (crashes AoT):

export function loadLazyModule() {
  return LazyModule;
}
export const appRoutes: Routes = [
  { path: 'lazy', loadChildren: loadLazyModule, },
];

实际上，错误消息根本没有帮助，但是堆栈跟踪为:

Indeed the error message is not helpful at all, however, the stack trace is:

at Compiler.compileModuleAsync (core.js:3664)
at MergeMapSubscriber.eval [as project] (router.js:4467)

我刚刚在compileModuleAsync函数中创建了一个断点，然后在停止处我看到了导致错误的模块.

I've just made a breakpoint at compileModuleAsync function and at the stop I saw the module which was causing the error.
