Firebase云功能模拟器出错

Question

我正在使用firebase cloud functions emulator。这是我的文件夹结构

├── firebase.json
├── functions
│   ├── etc
│   ├── index.js
│   ├── package.json
│   ├── src
│   │   ├── ArrayFromObject.ts
│   │   ├── Equations.ts
│   │   └── index.ts
│   ├── tsconfig.json
│   └── tslint.json
└── tree.txt

如果我位于主文件夹中，那么在firebase.json级别并运行sudo functions call helloWorld时，我会得到：

Error: { error:
{ code: 500,
    status: 'INTERNAL',
    message: 'Function worker crashed with exit code: 1\nundefinedWarning, estimating Firebase Config based on GCLOUD_PROJECT. Intializing firebase-admin may fail/usr/local/lib/node_modules/@google-cloud/functions-emulator/src/supervisor/worker.js:80\n      throw new Error(`No function found with name ${cloudfunction.entryPoint || name}`);\n      ^\n\nError: No function found with name helloWorld\n    at process.on (/usr/local/lib/node_modules/@google-cloud/functions-emulator/src/supervisor/worker.js:80:13)\n    at emitTwo (events.js:126:13)\n    at process.emit (events.js:214:7)\n    at emit (internal/child_process.js:772:12)\n    at _combinedTickCallback (internal/process/next_tick.js:141:11)\n    at process._tickCallback (internal/process/next_tick.js:180:9)',
    errors:
    [ 'Function worker crashed with exit code: 1\nundefinedWarning, estimating Firebase Config based on GCLOUD_PROJECT.

我不知道这是怎么回事。

如果我运行sudo函数，我会得到：

Google Cloud Functions Emulator RUNNING
┌────────┬────────────┬─────────┬────────────────────────────────────────────────────────┐
│ Status │ Name       │ Trigger │ Resource                                               │
├────────┼────────────┼─────────┼────────────────────────────────────────────────────────┤
│ READY  │ helloWorld │ HTTP    │ http://localhost:5000/uczsieapp/us-central1/helloWorld │
└────────┴────────────┴─────────┴────────────────────────────────────────────────────────┘

但是，如果我转到此网址，我会得到

如果我尝试从functions目录运行，则会发生相同的事情

这是我的helloWorld代码：

export const helloWorld = functions.https.onRequest((req, resp) => {
    return 'hello';
});

我想念什么？
