Question

使用 pip 安装依赖项时出现以下错误：

pip9.exceptions.InstallationError 命令“python setup.py egg_info”在 /tmp/tmpoons7qgkbuild/opencv-python/ 中失败，错误代码为 1

下面是在最近的 linux (5.4.0 x64) 系统上运行命令 pipenv install opencv-python 的结果。

Answer 1

如何修复 pip9.exceptions.InstallationError

确保 pip 和 setuptools 的版本足以满足 manylinux2014 wheels 。

A) 系统安装

sudo python3 -m pip install -U pip
sudo python3 -m pip install -U setuptools

B) 虚拟环境/Pipenv

 # Within the venv
pip3 install -U pip
pip3 install -U setuptools

解释

对我来说， python setup.py egg_info 可能因为python轮子最近的变化而失败，因为 manylinux1 wheels 被替换为 manylinux2014 wheels 根据 open-cv faq
