Firebase 模拟器无法以无意义的错误启动

Question

我们使用模拟器已有一段时间了。突然，他们停止了在两个开发人员（但不是所有开发人员）的机器上工作。他们尝试调用 firebase emulators:start，然后收到以下错误消息：Error: An unexpected error has occurred.

我们真的不知道为什么会这样。我们甚至尝试重做 firebase init 和 emulators init。到目前为止，我们所做的一切都无济于事。这是更多详细信息的控制台输出：

➜  firebase git:(dev-vab) ✗ firebase emulators:start
i  emulators: Starting emulators: functions, firestore, database, hosting, pubsub

现在，您会注意到我们确实检查了调试日志并发现了以下可能相关的内容：

}

这似乎是在抱怨我们在配置中指向本地模拟器，但不清楚为什么这会成为问题？

Answer 1

几个小时前我也遇到了这个问题。当我从 firebase.json 中删除主机时，它允许我正常启动模拟器，但我还没有弄清楚到底是什么导致了错误或如何在 json 之外正确设置主机文件.

Answer 2

解决此问题的另一种方法是将新的 firebase 身份验证模拟器添加到您的模拟器套件中。
