Firebase云函数仿真器未启动

Question

我一直在尝试使用云函数仿真器在本地测试我的云函数，但似乎不起作用。当我运行时会发生什么：

firebase emulators:start

我得到了以下信息：

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": {}
}

我试过运行firebase init和firebase init emulators几次，但到目前为止都没有成功。

登录的帐户对其具有编辑权限。请帮帮我，我真的需要这个。

Answer 1

我已经试过运行

，firebase init几次了，还有firebase init模拟器，但到目前为止都没有成功。

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，您可以检查您的节点版本和firebase版本吗？

下面的日志是我本地机器上的命令历史日志。

$ node -v
v10.20.1
$ firebase -V
8.2.0
$ firebase emulators:start
i  emulators: Starting emulators: firestore
i  firestore: downloading cloud-firestore-emulator-v1.11.3.jar...
Progress: ====================================================================================================> (100% of 64MB
i  firestore: Removing outdated emulator files: cloud-firestore-emulator-v1.10.2.jar
i  firestore: firestore emulator logging to firestore-debug.log
✔  firestore: firestore emulator started at http://localhost:8080
i  firestore: For testing set FIRESTORE_EMULATOR_HOST=localhost:8080
✔  emulators: All emulators started, it is now safe to connect.

firebase.json

{
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "emulators": {
    "firestore": {
      "port": 8080
    }
  }
}

Answer 2

我也看到了这一点，但是创建一个构建版本为我解决了这个问题，例如npm run build或yarn build

这将重新创建node_modules，并可能更新锁文件以同步依赖项
