[Python] error: subprocess-exited-with-error × Running setup.py install for lru-dict did not...

I am trying to build a container image with AWS EC2 Ubuntu to push on AWS ECR Repository for a python script which needs the web3.py library. However, it is throwing me an error that I'm not sure how to fix. I am using AWS ECR push commands to do it.

The command is: docker build -t docker-lambda .

My Dockerfile:

FROM public.ecr.aws/lambda/python:3.8

COPY requirements.txt ./

RUN pip3 install -r requirements.txt

COPY app.py ./

CMD ["app.lambda_handler"]


requirements.txt:

web3
