Python - AWS Lambda Function - Could not satisfied requirement

Question

I am just starting using AWS Lambda functions, and I come across this situation. I have the most basic python lambda function ( the Hello-World example ) generated from using sam init and when I use sam build I am receiving this error message :

' Build Failed Error: PythonPipBuilder:ResolveDependencies - Could not satisfy the requirement: requests '

The requirements.txt file contains only : requests and the tutorial used is here : https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-getting-started-hello-world.html

Please, help me with this situation.

Thank you!

I finally managed to solve it using the steps from this great tutorial : https://www.geeksforgeeks.org/how-to-install-python-packages-for-aws-lambda-layers/

Right now, in AWS you have access to Python3.9, so you would have to install it in the docker image + the appropriate bitarray module

Python3.9 installation: Will's answer from : How to install python3.9 on linux ubuntu terminal?

This step also : pip install --upgrade setuptools from : Pip error: Microsoft Visual C++ 14.0 is required

PS: python -c 'import bitarray; bitarray.test()' -> to test if the module is working

That tutorial may be great but it is almost impossible to read because of the animated ads on both sides.
