angular - NullInjectorError : No provider for t

Question

问候，我正在尝试使用“ng build --prod --configuration=production”构建我的 angular2 项目，将其部署在 ubuntu 服务器上，但在 Web 控制台中出现此错误:

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

我做了很多研究，似乎是 AppModule 中被遗忘的提供者的错

但是我找不到哪个服务...

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,
    IndexComponent,
    ResetComponent,
    PanelComponent,
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    AppRoutingModule,
    HttpClientModule,

    ReactiveFormsModule,
    RecaptchaModule,

    MatButtonModule,
    MatSnackBarModule,
    AgmCoreModule.forRoot({
      apiKey: environment.GOOGLE_MAP_API_KEY,
    })
  ],
  providers: [
    CookieService,
    Http,
    ToasterService,
    DisconnectedGuard,
    ConnectedGuard,
    AppRoutingModule,
    {
      provide: RECAPTCHA_SETTINGS,
      useValue: {
        siteKey: environment.GOOGLE_RECAPTCHA_API_KEY,
      } as RecaptchaSettings,
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

怎么解决，不知道怎么操作。

祝你有美好的一天，

我终于找到了解决方案(感谢@SouravDutta 提供线索)

转至 .\node_modules\@angular-devkit\build-angular\src\angular-cli-files\models\webpack-configs\common.js

评论以下...

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

再次重建项目并检查错误(更多信息现在给出)
(我有:EXCEPTION: Uncaught (in promise): Error: No provider for CookieOptions!)
这是我的 AppModule.ts 中缺少的提供程序

为了解决缺少的提供者...

我加CookieOptions到我的 import { CookieService, CookieOptions } from 'angular2-cookie/core';在 AppModule 中。

添加到我的提供商列表 { provide: CookieOptions, useValue: {} }

完毕。
