【问题描述】：
我正在使用 Firebase，并已开始尝试使用 Firebase 模拟器运行本地开发实例。我正在运行 Firebase 工具的 v8.4.1。当我使用真正的 Firestore 数据库运行时，一切正常。但是，当我使用模拟器时出现问题。
我可以 set 一个文档，然后通过 Javascript get 它，但在 Firebase Emulators UI 中什么也没有显示，反之亦然，当我通过 Firebase Emulators UI 添加数据时，它无法使用 get在 Javascript 中。此外，当我使用 Firebase Tools CLI 的导入和导出功能时，我通过 Javascript 添加的任何数据都不会被导出和导入。我在浏览器控制台中没有收到任何错误。
我不确定我在初始化 Firebase 时是否做错了什么或者我缺少其他一些配置？
我正在跑步：firebase emulators:start --only functions,firestore
Firebase 设置代码
import * as firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';
import 'firebase/functions';
const db = firebase.initializeApp({
apiKey: 'my_api_key',
appId: 'my_app_id',
authDomain: 'my_auth_domain',
databaseURL: 'my_database_url',
messagingSenderId: 'my_messaging_sender_id',
projectId: 'my_project_id',
storageBucket: 'my_storage_bucket',
}).firestore();
if (process.env.NODE_ENV === 'development') {
firebase.setLogLevel('debug');
db.settings({
host: 'localhost:8000',
ssl: false,
});
firebase.functions().useFunctionsEmulator('http://localhost:5001');
}
export { db };
