[anjanvb]

Describe the bug
I am trying to get ducks to install in a Docker for AWS Lambda, I see this error during the build process. The Docker image being used here is this lambda/python:3.9-x86_64 found here https://gallery.ecr.aws/lambda/python.

To Reproduce
Steps to reproduce the behavior:

1. create a requirements.txt with ducks
2. Create a dockerfile as below

FROM public.ecr.aws/lambda/python:3.9-x86_64
COPY requirements.txt  .
RUN  pip3 install -r requirements.txt --target "${LAMBDA_TASK_ROOT}"

Expected behavior
The installation to work properly.

Desktop (please complete the following information):

• Linux, x86-64

@anjanvb cykhash requires a compiler, gcc. If you pip install it on a machine with gcc it should work. But Poetry still has trouble with cykhash due to lack of PEP 517 compatibility. @manimino this library fills a useful niche. Any chance of making installation work without compile?

[manimino]

Agreed, the compile hurdle is one that many people have hit. I will look into ways to improve this in future.
