Firebase Firestore 适用于真实数据库，但不适用于模拟器
Firebase Firestore works with real database but not emulator
我正在使用 Firebase 并已开始尝试 运行 使用 Firebase 模拟器的本地开发实例。我正在使用 Firebase 工具的 运行ning v8.4.1。当我是 运行 真正的 Firestore 数据库时，一切正常。但是，当我使用模拟器时出现了问题。
我可以 set 一个文档，然后 get 它通过 Javascript 但是在 Firebase Emulators UI 中什么也没有显示，相反，当我添加数据时通过 Firebase 模拟器 UI 在 Javascript 中使用 get 不可用。此外，当我使用 Firebase Tools CLI 的导入和导出功能时，我通过 Javascript 添加的数据的 none 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 时是否有问题或我遗漏了一些其他配置？
我是 运行宁：firebase emulators:start --only functions,firestore

原来问题是由 Firebase 工具的当前状态引起的。我之前一直在另一个项目中使用 Firebase 工具，并且不得不 运行 我当前项目的 use 命令，我试图将模拟器与以下项目一起使用：
firebase use project_name
现在一切正常。
