Firebase nodejs 服务错误“AssertionError [ERR_ASSERTION]：缺少路径”

Question

发出命令“firebase serve --only functions,hosting”后出现以下错误消息

!  AssertionError [ERR_ASSERTION]: missing path

下面是我执行的命令

1. firebase 服务 --only 功能，托管
   收到一条消息，我需要从 6.4.0 -> 6.9.2 更新“运行 npm i -g firebase-tools 进行更新”

2. 再次更新后运行服务并收到消息“更新可用 6.9.2 → 6.10.0”，我再次运行更新。

3. 更新了 firebase-admin 以及“npm i -g firebase-admin@latest”

4. 再次运行“firebase serve --only 功能，托管”开始在 firebase-functions-test 上看到以下消息。在函数文件夹中运行提到的命令。

+  functions: Using node@8 from host.
+  functions: Emulator started at http://localhost:5001
i  functions: Watching "D:\BigData\13. Firebase\FB-BTD\FB-BTD\functions" for Cloud Functions...
i  hosting: Serving hosting files from: public
+  hosting: Local server: http://localhost:5000
!  The Cloud Functions emulator requires the module "firebase-functions-test" to be installed as a development dependency. To fix this, run "npm install --save-dev firebase-functions-test" in your functions directory.
i  functions: Your functions could not be parsed due to an issue with your node_modules (see above)
[hosting] Rewriting / to http://localhost:5001/btd-in2-20180718/us-central1/app for local Function app
i  functions: Beginning execution of "app"
!  The Cloud Functions emulator requires the module "firebase-functions-test" to be installed as a development dependency. To fix this, run "npm install --save-dev firebase-functions-test" in your functions directory.

5. 下次我运行 firebase serve 时，我收到了上述错误消息。

因此，我无法在本地测试 web nodejs firebase 代码。
