Can't resolve all parameters for anything:

For whatever reason I cannot automatically resolve anything in the constructor of services, components, ect. I have other projects that don't have this problem.

For example a component with the following constructor:

constructor(
    private location: Location
) {

results in the following error: Can't resolve all parameters for SearchQueryComponent: (?).

As a workaround I've been doing the following: 

constructor(
    @Inject(forwardRef(() => Location)) private location: Location
) {

What am I missing? Every other project I've worked on in angular does not require the decorators to resolve injectables.

My tsproject.json does have experimentalDecorators and emitDecoratorMetadata set to true.

polyfills.ts:

import 'core-js/es6/reflect';
import 'core-js/es7/reflect';
import 'zone.js/dist/zone';

after reviewing the example provided by @jb-nizet. Found that the import './polyfills'; was not imported first in the main.ts file.

Changed main.ts from:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
import './polyfills';

to 

import './polyfills';
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

Everything works!
