语法错误：请求的模块“@aws-amplify/platform-core”不提供名为“CallerDirectoryExtractor”的导出

Question

我使用 gen2 创建了一个 lambda 函数，如下所示：

amplify/functions/send-link-file/resource.ts 文件：

import { defineFunction } from '@aws-amplify/backend';
export const sendReportEmail = defineFunction({
  name: 'send-report-email',
  entry: './handler.ts',
  timeoutSeconds: 180
});

hander.ts 文件：

import {SendRawEmailCommand, SESClient, } from '@aws-sdk/client-ses';
import { CreateForm1 } from './pdf';
const sesClient = new SESClient({region: 'ap-south-1'});
export const handler = async (event: any, context: any) =\> {
\------ rest of the logic...
return 'success';
}

backend.ts 文件：

import { defineBackend } from '@aws-amplify/backend';
import {Effect, PolicyStatement} from "aws-cdk-lib/aws-iam"
import { auth } from './auth/resource.js';
import { data } from './data/resource.js';
import { sendLinkEmail } from './functions/send-link-email/resource';
import { sendReportEmail } from './functions/send-report-email/resource';
const backend = defineBackend({
auth,
data,
sendLinkEmail,
sendReportEmail
});

沙盒中一切运行良好。但是在部署时，我收到以下错误：

如何解决这个问题？

我正在尝试使用 aws amplify gen2 函数。 `

Answer 1

这一定是版本不同的问题， 确保所有 Amplify 软件包（尤其是

@aws-amplify/backend-function

和

@aws-amplify/platform-core

）兼容，方法是将它们更新到

package.json

中的相同版本，然后重新部署

npm install @aws-amplify/backend-function @aws-amplify/platform-core@latest --save

有时，陈旧或损坏的软件包安装可能会导致问题。您可以清除

npm cache

并重新安装依赖项：

npm cache clean --force
rm -rf node_modules
npm install
