CDKTF not recognizing libraries outside of python standard library

Question

I am unable to run cdktf because cdktf won't work with packages installed from PyPI. I need cdktf to be able to install / access packages installed from PyPI.

$ cdktf diff

boto3 is installed in my python virtual env. I also added boto3 to the Pipfile. I am unclear how to install packages listed under [packages] in the Pipfile. My Pipfile contains the following

[[source]]
name = "pypi"
url = "https://pypi.org/simple"
verify_ssl = true

[requires]
python_version = "3"

[packages]
cdktf = "~=0.13.3"
pytest = "*"
boto3 = "1.26.6"

As you have a Pipfile I'd expect your app command in your cdktf.json looks something like this: pipenv run python main.py . As you can see python is executed through Pipenv . You can use pipenv install to install the dependencies and then use it as you normally would in your python program.
