1. 确认在code build中安装了正确的版本的AWS CLI

   version: 0.2 phases: install: runtime-versions: python: 3.8 commands: - pip install awscli --upgrade --user pre_build: commands: - echo Check if the AWS CLI is installed - aws --version

2. 确认您的IAM角色（或IAM用户）具有足够的权限来执行您的CloudFormation堆栈。

3. 如果您在Pipeline Stage中使用的Codebuild是在VPC中，则需要为构建环境配置服务角色以访问VPC，Lambda，S3，ECS，EKS等。可以使用AWS的“AmazonElasticContainerServiceFullAccess”策略，如下所示：

   trusts:

   • Service:
     • codebuild.amazonaws.com policies:
   • Statement:
     • Effect: Allow Action:
       • "ecr:*"
       • "cloudwatch:*"
       • "logs:*"
       • "logs:CreateLogGroup"
       • "logs:CreateLogStream"
       • "logs:PutLogEvents"
       • "codebuild:*"
       • "sns:*"
       • "sqs:*"
       • "s3:*"
       • "sts:*"
       • "cloudformation:*"
       • "iam:*"
       • "ecs:*"
       • "lambda:*"
       • "ssm:*"
       • "secretsmanager:*"
       • "events:*"
       • "ec2:*"
       • "autoscaling:*"
       • "elasticloadbalancing:*"
       • "elasticfilesystem:*"
       • "rds:*"
       • "elasticbeanstalk:*"
       • "elasticache:" Resource: ""

4. 最后，请确保您在CodePipeline设置中选择正确的存储库和分支。 例如，“源”阶段和“构建”阶段。

希望这些步骤有助于解决AWS Code Pipeline上Amazon CloudFormation CDK的错误。
