AWSCDK-S3到Lambda：創建S3EventSource且存盤桶回傳`Property'_resource'ismissingintype`錯誤

我正在嘗試創建一個 cdk 堆疊以s3:ObjectCreated:Put在 S3 上發生事件后觸發 lambda 。

我下面一些教程（像這樣的一個），但我不能夠使事件源的創作S3EventSource作品，我收到的時候我試圖桶屬性添加到事件源的打字稿錯誤：

const s3PutEventSource = new S3EventSource(bucket, {
  events: [
    s3.EventType.OBJECT_CREATED_PUT
  ]
});

目前，我在 IDE 上以及嘗試運行npm run cdk deploy命令時收到以下錯誤：

lib/cdk-s3-stack.ts:29:48 - error TS2345: Argument of type 'import("/Users/jeprandini/cdk-s3/src/node_modules/@aws-cdk/aws-s3/lib/bucket").Bucket' is not assignable to parameter of type 'import("/Users/jeprandini/cdk-s3/src/node_modules/@aws-cdk/aws-ec2/node_modules/@aws-cdk/aws-s3/lib/bucket").Bucket'.

我的堆疊代碼：

import * as cdk from '@aws-cdk/core';
import * as s3 from '@aws-cdk/aws-s3';
import { NodejsFunction } from '@aws-cdk/aws-lambda-nodejs';
import { S3EventSource} from '@aws-cdk/aws-lambda-event-sources';

export class S3ToLambdaCdkStack extends cdk.Stack {
 constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
  super(scope, id, props);

const BUCKET_NAME = 'demo-bucket'

// S3 bucket
const bucket = new s3.Bucket(this, BUCKET_NAME, {
  /**
   * The following properties ensure the bucket is properly 
   * deleted when we run cdk destroy */
  autoDeleteObjects: true,
  removalPolicy: cdk.RemovalPolicy.DESTROY
});

const lambdaReadStream = new NodejsFunction(this, 'readStream', {
  entry: 'lambda-fns/readStream/handler.js',
  handler: 'handler'
});


const s3eventSource = new S3EventSource(bucket, {
  events: [
    s3.EventType.OBJECT_CREATED_PUT
  ]
});

lambdaReadStream.addEventSource(s3eventSource);

// Outputs
new cdk.CfnOutput(this, 'BucketArn', { value: bucket.bucketArn });
new cdk.CfnOutput(this, 'LambdaFunctionArn', { value: lambdaReadStream.functionArn });
 }
}

uj5u.com熱心網友回復：

看起來您的cdk匯入中存在一些依賴項沖突，對于某些依賴項，您正在使用該版本，1.127.0而對于其他依賴項，您正在使用該版本1.95.1，例如@aws-cdk/aws-s3庫。

通常，您需要為所有 cdk 模塊使用相同的版本。嘗試?1.95.1為所有 CDK 模塊使用該版本。

為此，將 cdk 依賴項更改為 version ?1.95.1，使用該命令rm -rf node_modules洗掉您的node_modules目錄并運行npm i以重新創建該node_modules目錄并再次安裝您的模塊。

之后，您可以npm run cdk deploy毫無問題地運行該命令。
