尝试初始化 Cloud Firestore 时，firebase.firestore() 不是函数 [英] firebase.firestore() is not a function when trying to initialize Cloud Firestore

问题描述

当我尝试初始化 Firebase Cloud Firestore 时，遇到以下错误:

When I try to initialize Firebase Cloud Firestore, I ran into the following error:

未捕获的类型错误:WEBPACK_IMPORTED_MODULE_0_firebase.firestore 不是函数

Uncaught TypeError: WEBPACK_IMPORTED_MODULE_0_firebase.firestore is not a function

我之前使用 npm install firebase --save 安装了 firebase.

I installed firebase with npm install firebase --save previously.

import * as firebase from 'firebase';
import router from '../router';

const config = {
        apiKey: "a",
        authDomain: "a",
        databaseURL: "a",
        projectId: "a",
        storageBucket: "a",
        messagingSenderId: "a"
};
if(!firebase.apps.length){
  firebase.initializeApp(config);
  let firestore = firebase.firestore();
}

推荐答案

我通过导入多个库来修复它:firebase 和 firebase/firestore.这是因为 firebase 核心库不包含 Firestore 库.

I fixed it by importing multiple libraries: firebase and firebase/firestore. That's because the firebase core library does not include the firestore library.

import firebase from 'firebase/app';
import 'firebase/firestore';
