Error encountered resolving symbol values statically #4956

This is an Angular compiler problem really not CLI problem. convert any lambda |
|
@Meligy There seems to be a lot of confusion in regards to the AOT compiler, myself included. I am also running into some of these errors. Is there a guide anywhere on how to use the AOT compiler with angular cli? I see in the Angular guide https://angular.io/docs/ts/latest/cookbook/aot-compiler.html they recommend creating a separate tsconfig, I have also read in the change log a while back that AOT is default when using |
|
you can turn AOT off by saying The goal of AOT in the CLI is to abstract it away so that you don't have to think about it. If you want a better understanding of what the AOT compiler is/does that article you posted should do a good job walking you through the steps. There is no tsconfig.aot.json because the cli is handling all of this for you in memory, behind the scenes. The docs for the cli are getting a lot of focus so things should improve in that regard. |
|
@deebloo, Thanks for the response. That at least clears up my confusion about tsconfig-aot.json. I will be looking forward to those updated docs. |

Heya, errors like The CLI always runs statical analysis on code to ensure it will run when compiled with AOT. This may cause a lot of static analysis errors to surface when importing your project into the CLI, or upgrading for older versions where we didn't run this kind of analysis. A good resource on how to to debug these errors is https://github.com/rangle/angular-2-aot-sandbox#aot-dos-and-donts. Also, the examples shown in https://angular.io/docs/ts/latest/cookbook/aot-compiler.html are not using the CLI so they are very different. |
|
This is like the 6th different error i have gotten while trying to configure AOT. The angular team should not put out code until it has been properly tested. |

I've been getting stuck on this issue with the error
I don't understand what's going on. Originally my file included export const testIndexedDBCache = new InjectionToken('testIndexedDBCache');
export let testIndexedDBCacheProvider : Provider = {
provide: testIndexedDBCache,
useFactory: () => new IndexedDBCache('test')
// ^--- position of error
};But even when I change the arrow function it still gets stuck on the same position! export const testIndexedDBCache = new InjectionToken('testIndexedDBCache');
export let testIndexedDBCacheProvider : Provider = {
provide: testIndexedDBCache,
useFactory: function() { return new IndexedDBCache('test'); }
// ^--- position of error
}; |

Karasuni, Angular 2 AOT is broken right now. I wasted over a week trying to update my project to work with AOT. Now I am extremely far behind, and AOT still doesn't work. My advice is to just use the Uglify plugin. |
|
I have a project that has been ejected to Webpack that seems to build AoT ok, but when I use NGC manually I run into this error. What's the difference? |
|
I get this error, when i first run build watch, but later when i change a file, it builds fine, :/ strange
|
|
Is AOT even worth all the pain it causes? Why does angular need this while other libraries are doing just fine without it? Looks a lot like a fix to a problem that shouldn't exist. |
|
@lifenautjoe probably because Angular is a few times larger than other libraries that do the same job, like vue.js. To be more precise, vue.js supports AOT through its loaders out of the box, but people usually don't even know that (maybe because vue.js is much smaller even without AOT so they don't feel it makes much difference, or because Angular causes so much pain while trying to set it up, so you NEED to talk about it). |
|
Without going into too much details, I worked around this by doing what the error's details suggested. Code that was erring out is: Fixed by creating a function and exporting it that creates an array out of the object |
|
@irtazabbas i tried your solution, compiling is ok, but modules are not imported |

With the option |

@NgModule({
imports: [CommonModule]
})
export class StoreModule {
static provideStore(): ModuleWithProviders {
return {
ngModule: StoreModule,
providers: [ added some providers]
};
}
}throwing an error: I compared it with RouterModule in .ts and .js all the same. Tried to many of work arounds and nothing. Anybody? For example RouterModule: @NgModule({declarations: ROUTER_DIRECTIVES, exports: ROUTER_DIRECTIVES})
export class RouterModule {
constructor(@Optional() @Inject(ROUTER_FORROOT_GUARD) guard: any, @Optional() router: Router) {}
static forChild(routes: Routes): ModuleWithProviders {
return {ngModule: RouterModule, providers: [provideRoutes(routes)]};
}
}If this thing will not be resolved I will not have any other way just to drop Angular support and stay only in react since this issue with ngc aot is very old. More than that - when compiling AOT with webpack all works fine, just after upgrading to Angular 5.0.0 ngc-weback plugin is not working any more. here is complete code of ng-state.module.ts: import { Inject, Injector, ModuleWithProviders, NgModule, InjectionToken } from '@angular/core';

@vytautas-pranskunas- I know what you mean. the AOT team seems to be in denial about the scope of the bug issue. One time, a legitimate issue was raised, and the bug was closed, with the comment "Thats the way it works". If you dont have the time or resources to fix the issue, i understand. But to just close it, when many people report the same thing. |
|
i too have same issue |
|
I'm trying using a subject on my route and it's cause the same issue. |
|
I also met with the same issue has anybody resoved this type of issue when running in (ng build --prod ) my angular version is 4 |
|
Hi , did anybody find the solution for that , i too get the same issue. It is strange we can able to run it when we run as "ng build --env=prod". But facing issue with ng build --prod. Are they both same . |
