cdk管线获取错误

Question

import * as cdk from '@aws-cdk/core';
import * as pipelines from '@aws-cdk/pipelines';


class PipelineStack extends cdk.Stack {
    constructor(scope: cdk.Construct, id: string, props: cdk.StageProps) {
      super(scope, id, props);
  
      // Create the CDK pipeline
      const pipeline = new pipelines.CodePipeline(this, 'Pipeline', {
        pipelineName: 'ServerlessPipelineDemo',
        synth: new pipelines.ShellStep('Synth', {
          // Use a connection created using the AWS console to authenticate to GitHub
          // Other sources are available.
          input: CodePipelineSource.connection('taimos/cdk-serverless-demo-pipeline', 'main', {
            connectionArn: 'arn:aws:codestar-connections:us-east-1:222222222222:connection/abc', // Created using the AWS console
          }),
          commands: [
            'npm ci && npm ci --prefix lambda',
            'npx cdk synth',
          ],
        }),
      });
    }
  }

我在行const pipeline = new pipelines.CodePipeline(this,中有一个错误

错误是：' this‘类型的参数不能分配给'PipelineStack’类型的参数。类型‘PipelineStack’不能分配到'onValidate‘类型。属性’onValidate‘是受保护的，但是类型’onValidate‘不是从’构造‘派生出来的类。

您的问题可能是与package.json cdk依赖关系版本不匹配。核心包( Construct位于v1中)被设置为版本1.74，与管道的版本不匹配。这有时会导致兼容性错误。要修复它，请将一个^添加到所有@aws-cdk依赖项中。

"@aws-cdk/core": "1.74.0"           // exactly 1.74
"@aws-cdk/pipelines": "^1.95.1"     // compatible with v1.95

当前CDK版本分别为1.137和2.3.0 (截至2022年1月)。
