Приведенный ниже сценарий блокирует мой прогресс в настройке моего приложения Flask, кто-нибудь знает об этом? ниже приведена важная информация.

Я уже вижу, как установить для файла LLVM_CONFIG правильный путь, но какой путь и как это сделать во время процесса сборки docker?

• pip 20.2.3

• python 3.8

Ниже 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 
     amp;amp; 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 
     amp;amp; 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"]
  

Ниже ошибка:

  ERROR: Failed building wheel for llvmlite
  

Во-первых, LLVM-Lite требует LLVM.

Итак, для этого необходимо правильно установить LLVM:

 RUN apt-get update amp;amp; apt-get install -y 
    build-essential 
    libedit-dev  
    llvm-{version} 
    llvm-{version}-dev
  

Затем установите переменную среды, используемую при сборке LLVM-Lite, и установите pip пакет:

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

Это решит вашу проблему.
