您需要从标记中删除:

   <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-app.js"
    ></script>
    <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-firestore.js"
    ></script>

    <script type="module" src="js/editor.js">
      firebase.initializeApp({
        apiKey: "AIzaSyBbHBS9rdHrbP6g7BG4_kPP9XV1vCiVewU",
        authDomain: "blog-web-49668.firebaseapp.com",
        projectId: "blog-web-49668",
        storageBucket: "blog-web-49668.appspot.com",
        messagingSenderId: "561111016179",
        appId: "1:561111016179:web:eef336738659e3fbfb0d86",
      });

      var db = firebase.firestore();
      db.settings({ timestampsInSnapshots: true });
    </script>

应为

   <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-app.js"
    ></script>
    <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-firestore.js"
    ></script>

    <script type="module" src="js/editor.js">
      firebase.initializeApp({
        apiKey: "AIzaSyBbHBS9rdHrbP6g7BG4_kPP9XV1vCiVewU",
        authDomain: "blog-web-49668.firebaseapp.com",
        projectId: "blog-web-49668",
        storageBucket: "blog-web-49668.appspot.com",
        messagingSenderId: "561111016179",
        appId: "1:561111016179:web:eef336738659e3fbfb0d86",
      });

      var db = firebase.firestore();
      db.settings({ timestampsInSnapshots: true });
    </script>

我有同样的问题，我用这种方法解决

你好，请尝试将此代码放在“firebase.js”中:

   <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-app.js"
    ></script>
    <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-firestore.js"
    ></script>

    <script type="module" src="js/editor.js">
      firebase.initializeApp({
        apiKey: "AIzaSyBbHBS9rdHrbP6g7BG4_kPP9XV1vCiVewU",
        authDomain: "blog-web-49668.firebaseapp.com",
        projectId: "blog-web-49668",
        storageBucket: "blog-web-49668.appspot.com",
        messagingSenderId: "561111016179",
        appId: "1:561111016179:web:eef336738659e3fbfb0d86",
      });

      var db = firebase.firestore();
      db.settings({ timestampsInSnapshots: true });
    </script>

并在js文件中导入:

   <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-app.js"
    ></script>
    <script
      type="module"
      src="https://www.gstatic.com/firebasejs/9.1.0/firebase-firestore.js"
    ></script>

    <script type="module" src="js/editor.js">
      firebase.initializeApp({
        apiKey: "AIzaSyBbHBS9rdHrbP6g7BG4_kPP9XV1vCiVewU",
        authDomain: "blog-web-49668.firebaseapp.com",
        projectId: "blog-web-49668",
        storageBucket: "blog-web-49668.appspot.com",
        messagingSenderId: "561111016179",
        appId: "1:561111016179:web:eef336738659e3fbfb0d86",
      });

      var db = firebase.firestore();
      db.settings({ timestampsInSnapshots: true });
    </script>
