Angular9：目标入口点“ @ angular / fire / auth”中的错误缺少相关性

Question

当我运行npm run start时，出现有关firebase的以下错误。

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

要注意的依赖性：

"@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Firebase / firestore和Angular 9从我的应用中获取的代码：

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与我的另一个前几天工作的项目进行了比较。

我发现Firebase软件包不存在。所以我只是将其复制进来，

“ firebase”：“ ^ 7.13.2”，

运行

npm安装

似乎可行：

package.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"
  },

现在我看到您有一个较旧的版本，也许可以解决该问题进行更新？

Answer 2

TL; DR
您需要两个软件包（@angular/fire和firebase）才能正常运行 您的应用，然后使用firebase / firestore。
使用ng add @angular/fire和npm install firebase

安装它们

说明：

我在为我的应用程序投放服务时遇到此错误。

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

此错误的原因：正确的 firebase角度设置 需要两个软件包@angular/fire和firebase。我仅使用ng add @angular/fire安装了其中之一。为了成功运行我的项目，我必须使用firebase安装npm install firebase软件包，并且此后可以正常工作。

Answer 3

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

npm的当前版本默认使用--save标志，因此它将自动更改package.json。

Answer 4

在您的应用程序中简单安装firebase。

npm install firebase --save

Answer 5

我必须面对同样的错误。

我刚刚安装了cli cli 8版本。 我以前的角度cli是10。

step 1> npm cache clean --force
step 2> npm uninstall -g @angular/cli
step 3> npm cache clean --force
step 4> npm install -g @angular/cli@8.1.0
step 5> ng new project_name
step 6> ng add @angular/fire firebase

希望一切都很好。

Answer 6

运行命令

npm i firebase@7.24.0

Answer 7

安装 Firebase，如下所示，也对我有用。
