【问题描述】：

我正在使用 vueJS 使用 Firebase 构建身份验证（登录）页面，每次运行时：npm run serve 我都有同样的错误要求我安装 Firebase：`Failed to compile with 7 errors 10:44:30上午

未找到这些依赖项：

./src/main.js 中的@firebase firebase 在 ./src/components/firebaseInit.js, ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/components /Login.vue 和其他 3 人 ./src/components/firebaseInit.js 中的 firebase/firestore。 并要求我安装 firebase：npm install --save @firebase firebase firebase/firestore。我做了很多次，但仍然是同样的错误。

这是我的 package.JSON：

节点-v = 16.12.1

npm -v =6.14.4

有什么想法吗？

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from "vue";
import App from "./App";
import router from "./router";
import firebase from "@firebase";
import "./components/firebaseInit";

Vue.config.productionTip = false;

let app;
firebase.auth().onAuthStateChanged(function(user) 
  if (!app) 
    /* eslint-disable no-new */
    app = new Vue(
      el: "#app",
      router,
      template: "<App/>",
      components:  App 
    );
  
);

firebaseInit.js

import firebase from 'firebase';
import 'firebase/firestore';
import firebaseConfig from './firebaseConfig';
const firebaseApp = firebase.initializeApp(firebaseConfig);
export default firebaseApp.firestore();

【问题讨论】：

能否分享main.js和firebaseInit.js的完整代码？

确保您遵循文档中的“使用模块捆绑器”设置，位于此处firebase.google.com/docs/web/setup

我刚刚添加了所需的文件

【参考方案1】：

我找到了，只需将 "firebase": "^7.13.1" 替换为 "firebase": "7.13.1". 即可。 我不知道为什么，但它奏效了！

【参考方案2】：

import  initializeApp  from 'firebase/app'
import  firebaseConfig  from './config'

initializeApp(firebaseConfig)

请分享有关您的安装过程的更多详细信息。您粘贴的代码是您希望如何使用该库，而不是您应该如何安装它们。 （除非你真的不知道如何安装。）
