无法使用 Python 中的现有 VPC 使用 CDK 创建 EC2

Question

尝试通过 CDK 2.0 访问 VPC，使用 python

from constructs import Construct

dirname = os.path.dirname(__file__)


class EC2InstanceStack(Stack):

    def __init__(self, scope: Construct, id: str, **kwargs) -> None:
        super().__init__(scope, id, **kwargs)

        vpc = ec2.Vpc.from_lookup(self, "vpc", vpc_id='vpc-0912xxxxxxx94647')

出现以下错误，不确定如何在我的代码中传递帐户和区域

任何想法？？

看起来答案在您的错误消息中:)
