类型{production：Boolean；}上不存在属性“FireBase”

Question

因此，我试图在Firebase和Heroku上构建和部署Angular 4应用程序，但我遇到了如下错误：

/Users/.../...中出错（57,49）：属性“FireBase”在类型“{Production：Boolean；}”上不存在。

当我运行ng build--prod并且我的部署服务器工作得非常好时，就会出现这种情况。这里是我的app.module.ts文件，供参考：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { AngularFireModule } from 'angularfire2';
import { AngularFireDatabaseModule } from 'angularfire2/database';
import { Ng2ScrollimateModule } from 'ng2-scrollimate';
import { Ng2PageScrollModule } from 'ng2-page-scroll';

import { HttpModule } from '@angular/http';
import { trigger, state, style, animate, transition, keyframes } from '@angular/animations';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { environment } from '../environments/environment';

import { AppComponent } from './app.component';

import { LogoComponent } from './logo/logo.component';
import { InfoComponent } from './info/info.component';
import { AboutComponent } from './about/about.component';
import { DividerComponent } from './divider/divider.component';
import { ProficienciesComponent } from './proficiencies/proficiencies.component';
import { ProficiencyComponent } from './proficiency/proficiency.component';
import { PortfolioComponent } from './portfolio/portfolio.component';
import { ProjectComponent } from './project/project.component';
import { ResumeComponent } from './resume/resume.component';
import { FooterComponent } from './footer/footer.component';
import { ContactComponent } from './contact/contact.component';
import { LoadingComponent } from './loading/loading.component';

@NgModule({
  declarations: [
    AppComponent,
    LogoComponent,
    InfoComponent,
    AboutComponent,
    DividerComponent,
    ProficienciesComponent,
    ProficiencyComponent,
    PortfolioComponent,
    ProjectComponent,
    ResumeComponent,
    FooterComponent,
    ContactComponent,
    LoadingComponent,
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    BrowserAnimationsModule,
    AngularFireModule.initializeApp(environment.firebase),
    AngularFireDatabaseModule,
    Ng2ScrollimateModule,
    Ng2PageScrollModule.forRoot(),
  ],
  providers: [],
  bootstrap: [AppComponent],
})
export class AppModule {}

export const environment = {
  production: true
};

Environment.TS

export const environment = {
  production: true,
  firebase: {
    apiKey: '...',
    authDomain: 'project.firebaseapp.com',
    databaseURL: 'https://project.firebaseio.com',
    projectId: 'project',
    storageBucket: 'project.appspot.com',
    messagingSenderId: '...',
  },
};

在搜索StackOverflow和GitHub以寻找可能的解决方案之后，似乎没有开发人员遇到过这个确切的错误并公布了他们的发现，所以我想知道是否有人知道如何着手解决这个问题。提前谢谢你！

运行NG Build--prodAngular-CLI将使用Environment.prod.ts文件，而Environment.prod.tsfilesEnvironment变量没有Firebase字段，因此会出现异常。

将该字段添加到environment.prod.ts

export const environment = {
  production: true,
  firebase: {
    apiKey: '...',
    authDomain: 'project.firebaseapp.com',
    databaseURL: 'https://project.firebaseio.com',
    projectId: 'project',
    storageBucket: 'project.appspot.com',
    messagingSenderId: '...',
  },
};
