Firebase Cloud Function仿真器未启动

Question

我一直在尝试使用云功能仿真器在本地测试我的云功能，但是它似乎不起作用。我跑步时会发生什么：

firebase emulators:start

我得到以下内容：

i  emulators: Starting emulators: functions
+  hub: emulator hub started at http://localhost:4400
i  emulators: Shutting down emulators.
i  hub: Stopping emulator hub

Error: An unexpected error has occurred.

Having trouble? Try again or contact support with contents of firebase-debug.log

这是我的firebase.json的样子：

{
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ]
  },
  "emulators": {}
}

我尝试运行firebase init几次，也尝试过firebase init emulators，但到目前为止都没有工作。

已登录并拥有编辑者权限的帐户。请帮助我，我非常需要这个。

我已经尝试运行过几次，运行过firebase init，也尝试过运行firebase init模拟器，但到目前为止，它们都没有起作用。

请参见https://firebase.google.com/docs/emulator-suite/install_and_configure。

You will need CLI version 7.8.0 or higher to use the Emulator Sute.

首先，您能否检查您的节点版本和Firebase版本？

以下日志是本地计算机上的命令历史记录日志。

$ node -v

$ firebase -V

$ firebase emulators:start
