How to Reproduce

I followed the steps in the DDK workshop, and ran into the following issue when running ddk deploy:

Deploying DDK stacks to AWS account 619876764317 and region us-east-1...
Traceback (most recent call last):
  File "app.py", line 3, in <module>
    import aws_cdk as cdk
ModuleNotFoundError: No module named 'aws_cdk'

My assumption was that it was related to the virtual environment, and ddk running the wrong version. This proved correct when I ran which ddk, as it printed a reference to the ddk installation outside the virtual env.

I then tried to run cdk deploy instead. However, it failed with the following error:

Traceback (most recent call last):
  File "app.py", line 3, in <module>
    import aws_cdk as cdk
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/__init__.py", line 24837, in <module>
    from . import aws_apigateway
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/aws_apigateway/__init__.py", line 1565, in <module>
    from ..aws_certificatemanager import ICertificate as _ICertificate_c194c70b
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/aws_certificatemanager/__init__.py", line 184, in <module>
    from ..aws_cloudwatch import (
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/aws_cloudwatch/__init__.py", line 602, in <module>
    from ..aws_iam import Grant as _Grant_a7ae64f8, IGrantable as _IGrantable_71c4f5de
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/aws_iam/__init__.py", line 662, in <module>
    class AddToPrincipalPolicyResult:
  File "/Users/lutleon/Projects/ddk-demo/sample-app/.venv/lib/python3.8/site-packages/aws_cdk/aws_iam/__init__.py", line 667, in AddToPrincipalPolicyResult
    policy_dependable: typing.Optional[constructs.IDependable] = None,
AttributeError: module 'constructs' has no attribute 'IDependable'

I was able to mitigate this by running pip install aws_cdk.constructs. After I ran that command, cdk deploy was able to synthesize the resources and show the diff.

I am on version 2.34.0 (build 633edab) of CDK. Additionally, the Python library for aws-cdk-lib is on version 2.29.0.

Upgrading CDK to version 2.34.2 fixed the problem with cdk deploy.
