NullInjectorError：没有t的提供者

Question

问候，我正在尝试用“ng build --prod --configuration = production”构建我的angular2项目，将它部署在ubuntu服务器上，我在Web控制台中遇到了这个错误：

ERROR Error: "StaticInjectorError[t -> t]: 
  StaticInjectorError(Platform: core)[t -> t]:

我做了很多研究，似乎这是AppModule中一个被遗忘的提供者的错

但我找不到哪个服务......

import { AgmCoreModule } from '@agm/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { MatButtonModule, MatSnackBarModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { Http } from './service/http.service';
import { ToasterService } from './service/toaster.service';
import { ConnectedGuard } from './service/connected-guard.service';
import { DisconnectedGuard } from './service/disconnected-guard.service';
import { AppComponent } from './app.component';
import { LoginComponent } from './view/login/login.component';
import { RegisterComponent } from './view/register/register.component';
import { IndexComponent } from './view/index/index.component';
import { ResetComponent } from './view/reset/reset.component';
import { AppRoutingModule } from './app-routing.module';
import { CookieService } from 'angular2-cookie/services/cookies.service';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { RecaptchaModule, RECAPTCHA_SETTINGS, RecaptchaSettings } from 'ng-recaptcha';
import { RecaptchaFormsModule } from 'ng-recaptcha/forms';
import { environment } from 'src/environments/environment';
import { PanelComponent } from './component/panel/panel.component';

@NgModule({
  declarations: [
    AppComponent,
    LoginComponent,
    RegisterComponent,

      useValue: {
        siteKey: environment.GOOGLE_RECAPTCHA_API_KEY,
      } as RecaptchaSettings,
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

我如何找到解决方案，我不知道如何操作。

祝你有美好的一天，

Answer 1

我终于找到了解决方案（谢谢@SouravDutta的线索）

1. 去.\node_modules\@angular-devkit\build-angular\src\angular-cli-files\models\webpack-configs\common.js
2. 评论以下......

/*extraMinimizers.push(new TerserPlugin({
   sourceMap: scriptsSourceMap,
   parallel: true,
   cache: true,
   terserOptions,
}));*/ 

3. 重新重建项目并检查错误（现在给出更多信息）（我有：EXCEPTION: Uncaught (in promise): Error: No provider for CookieOptions!）我的AppModule.ts中缺少提供者

---

解决那个缺少的提供者......

1. 我将CookieOptions添加到AppModule中的import { CookieService, CookieOptions } from 'angular2-cookie/core';中。
2. 加入我的提供者列表{ provide: CookieOptions, useValue: {} }

完成。
