无法在本地测试云功能，模拟器无法以TypeError开头：_onRequestWithOpts不是函数

Question

当我尝试从项目中的functions目录启动外壳程序进行本地测试时，模拟器会启动，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。怎么了？

我尝试删除功能目录并使用firebase-tools cli再次创建它，但仍然出现相同的错误。我还导出了管理员凭据。

我正在使用从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!");
});

我希望仿真器启动该函数的实例进行测试，但相反，我看到此错误：

?  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.

Answer 1

如果遇到此错误，请npm install firebase-functions@3.0.2在functions目录中运行。

这将很快得到修复，您可以在此处进行以下操作：https : //github.com/firebase/firebase-tools/issues/1480
