typescript - 无法在本地测试云功能，模拟器无法启动并出现 TypeError : _onRequestWithOpts is not a function

Question

当我尝试从项目中的函数目录启动用于本地测试的 shell 时，模拟器启动但无法加载我的函数。

当我运行“npm run build”时，我没有收到任何错误。发生了什么事？

我尝试删除函数目录并使用 firebase-tools cli 重新创建它，但我仍然遇到相同的错误。我还导出了管理员凭据。

我使用的是在从 firebase-tools cli 生成的 index.ts 文件中创建的默认方法。

import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';

admin.initializeApp();
// // Start writing Firebase Functions
// // https://firebase.google.com/docs/functions/typescript
//
export const helloWorld = functions.https.onRequest((request, 
response) => {
 response.send("Hello from Firebase!");
});

我希望模拟器启动函数的实例进行测试，但相反，我看到了这个错误:

⚠  We were unable to load your functions code. (see above)
   - It appears your code is written in Typescript, which must be compiled before emulation.
   - You may be able to run "npm run build" in your functions directory to resolve this.

如果您遇到此错误，请在 functions 目录中运行 npm install firebase-functions@3.0.2。
