Errors when compiling using Ahead of Time

I get this error when I try to compile Ahead of Time in a project written in angular 2.

  

Error: Error at /xxx/app/src/bootstrap.aot.ts:2:36: Can not find module '../../ app-aot / app / src / app.module.ngfactory'.

This is my bootstrap.aot file:

  {
    "compilerOptions": {
      "target": "es5",
      "module": "es2015",
      "moduleResolution": "node",
      "sourceMap": false,
      "emitDecoratorMetadata": true,
      "experimentalDecorators": true,
      "removeComments": false,
      "noImplicitAny": false,
      "suppressImplicitAnyIndexErrors": true,
      "skipLibCheck": true,
      "typeRoots": [
        "node_modules/@types/"
      ]
    },
    "files": [
      "app/src/app.module.ts",
      "app/src/bootstrap.aot.ts"
    ],
  "angularCompilerOptions": {
    "genDir": "app-aot",
    "skipMetadataEmit" : true
  }
}

And this is my bootstrap configuration:

import { platformBrowser } from '@angular/platform-browser';
import { AppModuleNgFactory } from '../../app-aot/app/src/app.module.ngfactory';

platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);

The path of app.module.ngfactory is correct, for some reason the compiler does not generate the ngfactories of the app folder. I only see in the app-aot folder the ones related to the node_modules folder, I do not know what I can be doing wrong.

Has anyone encountered a similar problem?
