Python 7安装错误

Question

我有一个安装Pillow==8.4.0的python项目。在使用Docker进行本地测试时，它可以正常工作。

# Dockerfile
ARG PIP_CMD='pip install --no-cache-dir'

ARG APK_ADD='apk add --no-cache'

# PIL packages
ARG PIL_PKGS='jpeg-dev zlib-dev libjpeg'

ARG PKGS='git libpq openssh-client'

# development packages that will be installed before pip is run and purged after
ARG DEV_PKGS='linux-headers postgresql-dev python3-dev gcc g++ musl-dev libpng-dev libressl-dev libffi-dev'

$PIP_CMD --upgrade 'pip<20.3' && \
    if ! $PIP_CMD -r requirements.txt; then $APK_ADD $PKGS $PIL_PKGS && $APK_ADD --virtual .build-deps $DEV_PKGS && $PIP_CMD -r requirements.txt && apk del .build-deps; fi ...

我们使用python3.6 setup.py bdist_rpm作为rpm构建项目，然后将其安装在centos7框上。rpm的安装失败，因为它说该项目缺少依赖项(似乎是枕套)：

# yum install project-1.0

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我可以通过以下方式成功地将枕头直接安装在盒子上：

python3 -m pip install Pillow

我还尝试安装这里指定的依赖项( https://pillow.readthedocs.io/en/stable/installation.html )。

yum install zlib libjpeg

在安装project-1.0时仍然会看到上面的错误

我也尝试过像这里建议的那样，将一些*.so文件从/usr/lib64/...链接到/usr/lib/...：PIL /JPEG Library: "decoder jpeg not available"，但没有运气。

对下一步该做什么有什么建议吗？

安装Pillow==8.4.0时，这些库位于

/your_venv/lib/python3.6/site-packages/Pillow.libs/
