Failed to install llvm-lite with a Dockerfile

The scenario below is blocking me to have progressed in dockerize my Flask App, anybody has any clue about it? some important info below.

I already see about setting the LLVM_CONFIG file to the right path but which path and how to do that during the docker build process?

Below the Dockerfile:

FROM python:3.8-alpine
RUN adduser -D ddc-user
WORKDIR /ddc
COPY . /ddc
RUN echo "http://dl-8.alpinelinux.org/alpine/edge/community" >> /etc/apk/repositories \
     && apk --no-cache --update-cache add postgresql-dev g++ linux-headers gfortran libffi-dev openssl-dev gcc build-base bash libpng-dev openblas-dev wget freetype-dev python3-dev py3-pip \
     && ln -s /usr/include/locale.h /usr/include/xlocale.h
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl
RUN apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev
RUN pip install --upgrade pip
RUN pip install Pillow
RUN LLVM_CONFIG=/tmp/pip-install-3knaaqva/llvmlite/ffi/llvm-config pip install llvmlite==0.34.0
RUN apk add --no-cache --virtual .build-deps gcc musl-dev
RUN pip install numpy pyyaml
RUN pip install setuptools wheel
RUN pip install cython
RUN pip install -r requirements.txt
RUN chmod +x boot.sh
ENV FLASK_APP main.py
RUN chown -R ddc-user:users ./
USER ddc-user
EXPOSE 5000
ENTRYPOINT ["./boot.sh"]

Below the error:

Firstly, LLVM-Lite requires LLVM.

So, it's necessary to install the LLVM correctly, to do this:

RUN apt-get update && apt-get install -y \
    build-essential \
    libedit-dev  \
    llvm-{version} \
    llvm-{version}-dev

Then, set the environment variable used when building LLVM-Lite and install pip package:

RUN LLVM_CONFIG=/usr/bin/llvm-config-{version} pip install llvmlite=={version}

This will solve your problem.

To find out which version of LLVM is compatible with each version of LLVM-Lite go to:
