javascript - 无法为 VueJS + NodeJS 安装 Firebase

Question

我正在使用 vueJS 使用 Firebase 构建一个身份验证(登录)页面，每次运行时:npm run serve 我都会遇到同样的错误，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 个
• ./src/components/firebaseInit.js 中的 firebase/firestore。并要求我安装 firebase 执行以下操作: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:

Node -v = 16.12.1

npm -v =6.14.4

有什么想法吗？

主要.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();

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!
