ModuleNotFoundError: No module named aws_cdk

Question

When I run cdk deploy, I get the following error:

Traceback (most recent call last):
  File "app.py", line 3, in <module>
    from aws_cdk import core
ModuleNotFoundError: No module named 'aws_cdk'

I installed cdk with npm

npm install -g aws-cdk

I activated the virtual env by

source .env/bin/activate

I'm using python3.8. I installed aws_cdk dependencies by

pip install -r requirements.txt

When editing the python files, I am able to import aws_cdk and run individual functions successfully. I think the problem is that cdk is located in the /usr directory:

> which cdk
/usr/local/bin/cdk

And I think it's using python from my /usr/bin instead of virtual env. How do I make cdk use python in my virtual environment?

EDIT:

requirements.txt

-e .

Answer 1

install via cmd as below.

pip install aws-cdk.core

or

add following line in requirements.txt file

aws-cdk.core

it should resolved

Answer 2

I think you have to order

python -m pip install -r requirements.txt

This will install the standard dependencies for your CDK project.
