javascript - 如何修复vuejs中的 "ReferenceError: require is not defined"

Question

我正在开发一个 vuejs + firebase 项目，我试图导入 firestore，但是当我访问我的页面时，这会显示在控制台中:ReferenceError: require is not Define

我尝试将导入部分放入 Mounted() 中，但它说我需要将导入内容放在顶部，这就是我所做的

这是我的 html (register.html) 正文下面:

<script src="https://www.gstatic.com/firebasejs/6.4.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/6.4.0/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/6.4.0/firebase-firestore.js"></script>

<!-- TODO: Add SDKs for Firebase products that you want to use
     https://firebase.google.com/docs/web/setup#config-web-app -->

<script>
  // Your web app's Firebase configuration
  var firebaseConfig = {
    apiKey: "AIzaSyCNYH-sKZZXZhZt5LxQSDqwet7OTo5KgHM",
    authDomain: "thelogoagency-3a11d.firebaseapp.com",
    databaseURL: "https://thelogoagency-3a11d.firebaseio.com",
    projectId: "thelogoagency-3a11d",
    storageBucket: "",
    messagingSenderId: "101296201242",
    appId: "1:101296201242:web:00d0e7e3554b518d"
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);
</script>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="register.js"></script>

我的register.js 的顶部

// Required for side-effects
require("firebase/firestore");

var app = new Vue({
    el: "#root",
    data: {
        burgerClass: "navbar-burger",
        menuClass: "navbar-menu",
        mobileMenuIsActive: "",
        mobileMenuHasBeenClicked: false,
        firstNameInput: "",
        lastNameInput: "",
        emailInput: "",
        passwordInput: "",
        authError : "",
        emailErrorClass : "",
        emailErrorHelp : "",
        passwordErrorClass : "",
        passwordErrorHelp : "",
        inputClass: "input ",
        nameErrorHelp: "",
        isLoading: false,
        firebase: firebase,
        db: null,
        numberOfInit: 0
    },

并安装()

        if(this.numberOfInit = 0)
            firebase.initializeApp({
                apiKey: 'AIzaSyCNYH-sKZZXZhZt5LxQSDqwet7OTo5KgHM',
                authDomain: 'thelogoagency.tk',
                projectId: '1:101296201242:web:00d0e7e3554b518d'
            });

            this.db = firebase.firestore();
            this.numberOfInit ++
            this.db.collection("users").add({
                first: "Ada",
                last: "Lovelace",
                born: 1815
            })
            .then(function(docRef) {
                console.log("Document written with ID: ", docRef.id);
            })
            .catch(function(error) {
                console.error("Error adding document: ", error);
            });

    }

它通常应该工作正常，因为它是从 firebase 的文档复制的。我知道我可能做错了:)感谢您的帮助

如果您使用的是 Javascript 而不是 NodeJS，则只需将您的库链接到

<script src="https://my/lib.js"></script>

所以你可以删除你的 require 行:)
