Angular9：目标入口点“@angular/fire/auth”中的错误缺少依赖项

Question

当我运行 npm run start 时，出现以下有关 firebase 的错误。

技术：Angular 版本 9、Firebase、Firestore、Geofirestore Angular CLI。

错误：

ERROR in The target entry-point "@angular/fire/auth" has missing dependencies:
 - firebase/auth
 - firebase/app

需要注意的依赖：

"@angular/cli": "~9.1.1",
"@angular/core": "~9.1.1",
"@angular/fire": "^5.1.1",
"firebase": "5.10.1",
"geofirestore": "3.2.3",

错误屏幕抓取：

使用带有 Angular 9 的 firebase / firestore 的应用程序中的代码：

import * as firebase from 'firebase/app';
import * as _geoHash from 'latlon-geohash';
import { AngularFireDatabase } from '@angular/fire/database';
import { AngularFirestore } from '@angular/fire/firestore';
import { Injectable } from '@angular/core';
import { Observable, from, of } from 'rxjs';
import { GeoFirestore } from 'geofirestore';
import { map, take } from 'rxjs/operators';

import { FirebaseService } from '../services/firebase.service';
import { JobModel } from '../models/job.model';
import { StorageService } from '../services/storage.service';
import { UserService } from '../services/user.service';
import { UtilityService } from '../services/utility.service';

@Injectable()
export class JobService extends FirebaseService {
  public geo: any;
  public geofirestore: GeoFirestore;

  constructor(
    public angularFireDatabase: AngularFireDatabase,
    private angularFirestore: AngularFirestore,
    public storageService: StorageService,
    private userService: UserService,
    private utilityService: UtilityService
  ) {
    super(angularFireDatabase);

    const firestore = firebase.firestore();
    firestore.settings({ });
    this.geofirestore = new GeoFirestore(firestore);
  }

  public getCount(): any {
    const adzuna = firebase.firestore().collection('jobsCount').doc('adzuna');
    const hired = firebase.firestore().collection('jobsCount').doc('hired');

    return from(Promise.all([adzuna.get(), hired.get()])
      .then((querySnapshot) => {
        return { adzuna: querySnapshot[0].data(), hired: querySnapshot[1].data() };
      })
    );
  }
}

有同样的问题。将我的 package.json 与我前几天工作的另一个项目进行了比较。

我发现 firebase 包不在那里。所以我只是复制了它，

"firebase": "^7.13.2",

跑了

安装

它似乎有效：

包.json：

"dependencies": {
    "@angular/animations": "~9.1.0",
    "@angular/cdk": "^9.2.0",
    "@angular/common": "~9.1.0",
    "@angular/compiler": "~9.1.0",
    "@angular/core": "~9.1.0",
    "@angular/fire": "^6.0.0",
    "@angular/forms": "~9.1.0",
    "@angular/material": "^9.2.0",
    "@angular/platform-browser": "~9.1.0",
    "@angular/platform-browser-dynamic": "~9.1.0",
    "@angular/router": "~9.1.0",
    "firebase": "^7.13.2",
    "rxjs": "~6.5.4",
    "tslib": "^1.10.0",
    "zone.js": "~0.10.2"
  },

现在我看到你有一个旧版本，也许更新可以解决问题？

Answer 2

TL;DR
您需要两个包 ( @angular/fire& firebase) 才能正确运行您的应用程序，然后才能使用 firebase/firestore。
使用ng add @angular/fire&安装它们npm install firebase

解释：

当我提供我的应用程序时，我收到了这个错误。

ERROR in The target entry-point "@angular/fire" has missing dependencies:
 - firebase/app

此错误背后的原因：正确的firebase 角度设置需要两个包@angular/fire& firebase. 我只安装了其中一个使用ng add @angular/fire. 为了成功运行我的项目，我必须firebase使用npm install firebase& 它在此之后工作安装包。

只需在您的项目中更新/安装 Firebase（本地，而不是全局）。使用终端转到项目文件夹并执行：

npm install firebase@latest

当前版本的 npm 默认使用 --save 标志，因此它会自动更改 package.json。
