Angular CLI build prod optimizer got error.

[ghost]

Uncaught Error: StaticInjectorError[i]: StaticInjectorError[i]: NullInjectorError: No provider fori!``

The app work correctly when 'serve' or 'build' but got error 'StaticInjectorError' when build prod optimizer.

Same issue for me as well - NullInjectorError: No provider for class{}! serve and build work fine. build prod causes the error.

My local environment:

Angular CLI: 1.7.3
Node: 8.9.1
OS: darwin x64
Angular: 5.2.8
... animations, common, compiler, compiler-cli, core, forms
... http, platform-browser, platform-browser-dynamic
... platform-server, router

Same issue for me as well - StaticInjectorError[i]. With webpack 4 and Angular 6 to compile AOT (@ngtools_webpack)

I had this problem and it drove me nuts... i finally figured it out... by turning off build-optimizer ( for Es2015 targets - known bug) and source-maps on for --prod in angular.json which gave a error pointing me to, providing Options-Object for angular2-logger, in app.module.ts like:

import { Logger as FgLogService, Level, Options } from 'angular2-logger/core'; and import it in the provider-section: ... providers: [ ... // Provide Options-object for angular2-logger aka FgLogService { provide: Options, useValue: { store: false } }, ... ] ...

Hope this helps someone... i guess the problem is that uglify removes default options-object? But couldn't verify... would explain why it only breaks on build...
