Firebase 模拟器无法启动并出现无意义的错误

Question

我们使用模拟器已经有一段时间了。突然，他们停止在两个开发人员（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发生这种情况。我们甚至尝试重做 firebase init 和 emulators init。到目前为止，我们所做的一切尝试都没有帮助。以下是控制台输出以了解更多详细信息：

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：

它似乎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？

就在几个小时前，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，或者如何在 json 文件之外正确设置主机。
