类型 { production: boolean; 上不存在属性“firebase"} [英] Property 'firebase' does not exist on type { production: boolean; }

问题描述

所以我试图在 Firebase 和 Heroku 上构建和部署我的 Angular 4 应用程序以进行生产，但我遇到了如下错误:

So I was trying to build and deploy my Angular 4 app for production on both Firebase and Heroku, but I have come across the error as follows:

/Users/.../... (57,49) 中的错误:属性firebase"不存在在类型'{生产:布尔；}'.

ERROR in /Users/.../... (57,49): Property 'firebase' does not exist on type '{ production: boolean; }'.

当我运行 ng build --prod 时会发生这种情况，并且我的部署服务器运行良好.这是我的 app.module.ts 文件，供参考:

It occurs when I run ng build --prod, and my deployment servers are working perfectly fine. Here is my app.module.ts file, for reference:

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 {}

environment.prod.ts

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: '...',
  },
};

在搜索了 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发布了他们的发现，所以我想知道是否有人知道如何解决这个问题.提前非常感谢！

After scouring StackOverflow and GitHub for possible solutions, there seem to be no developers who have encountered this exact error and published their findings, so I was wondering whether anyone knows how to go about solving this issue. Thanks so much in advance!

推荐答案

当你运行 ng build --prod angular-cli 将使用 environment.prod.ts文件和您的 environment.prod.ts 文件 environment 变量没有 firebase 字段，因此您得到了异常.

When you run ng build --prod angular-cli will use the environment.prod.ts file and your environment.prod.ts files environment variable doesn't have the firebase field hence you are getting the exception.

将字段添加到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: '...',
  },
};
