Dockerizing Jamspell web app

[LGTiscar]

Hello, I have built a FastAPI web app with Jamspell as a training and learning how to code web apps. I want to dockerize it now, so I can run it in my MAC Air M1 and my Windows PC as well. As requirements for the image to build, I have this requirements.txt file:

swig==3.0.12
jamspell
fastapi
uvicorn

A virtual environment with this requirements.txt file works just fine, and installs both swig, jamspell and can run my web app. But when I try to build the docker image, with this dockerfile:

FROM python:3.11.1-slim-buster

WORKDIR /app

COPY corrector.py /app
COPY requirements.txt /app

RUN pip install -r requirements.txt

CMD ["uvicorn", "corrector:app", "--host", "0.0.0.0", "--port", "85"]

It throws an error while trying to install jamspell:

Is there any known bug when trying to dockerize Jamspell? I saw this line of the log:
assert swigBinary is not None
That is similar as the Issue of installing Jamspell on Mac with pip3. But I fixed it on my virtualenv specifying swig version in the requirements.txt. Somehow, it does not work on the docker building.

Sorry if I am missing any major or obvious step trying to dockerize it, I am fairly new to Docker :D

I think you'll need to switch to a non-slim image.
I had this issue when using FROM python:3.11-slim, and fixed it by switching to regular FROM python:3.11 (slim is missing some prerequisites for installing jamspell).
