通过无服务器失败进行打字稿编译

Question

我有一个基于 Typescript 的 Lambda 函数，可以正常编译，tsc但当我尝试通过无服务器部署时，Typescript 复杂性失败并出现以下错误：

Serverless: Running "serverless" installed locally (in service node_modules)
Serverless: Compiling with Typescript...
Serverless: Using local tsconfig.json
Serverless: Warning: "rootDir" from local tsconfig.json is overriden
Cannot locate handler - account. not found
 
  Error --------------------------------------------------
 
  Error: Typescript compilation failed. Please ensure handlers exists with ext .ts or .js
      at /Users/bob/Development/service-account/node_modules/serverless-plugin-typescript/src/typescript.ts:69:13

相关的代码块account.ts是：

Serverless: Running "serverless" installed locally (in service node_modules)
Serverless: Compiling with Typescript...
Serverless: Using local tsconfig.json
Serverless: Warning: "rootDir" from local tsconfig.json is overriden
Cannot locate handler - account. not found
 
  Error --------------------------------------------------
 
  Error: Typescript compilation failed. Please ensure handlers exists with ext .ts or .js
      at /Users/bob/Development/service-account/node_modules/serverless-plugin-typescript/src/typescript.ts:69:13

serverless.yml 文件的相关部分是：

import { APIGatewayProxyHandler, APIGatewayEvent, Context } from 'aws-lambda';
import 'source-map-support/register';

export const handler: APIGatewayProxyHandler = async (event: APIGatewayEvent, context: Context): Promise<any> => {
    console.debug(`event: ${JSON.stringify(event, null, 1)}`);
    console.debug(`context: ${JSON.stringify(context, null, 1)}`);
...
}

tsconfig.json 相当标准：

plugins:
  - serverless-iam-roles-per-function
  - serverless-plugin-typescript
  - serverless-webpack

service: accounts

custom:
  webpack:
    webpackConfig: ./webpack.config.js
    includeModules: true

functions:
  account:
    handler: account.handler
...

目录树如下所示：

config <dir>
dist <dir>
node_modules <dir>
src <dir>
  account.ts
swagger <dir>
package.json
tsconfig.json
webpack.config.js
serverless.yml

想知道我在连接所有点以使其在无服务器中工作时缺少什么吗？

Answer 1

您需要提供处理程序的相对路径，这应该可以工作

functions:
  account:
    handler: "./src/account.handler"

你可以选择省略./，但handler: "src/account.handler"也应该工作。
