Question

pip9.exceptions.InstallationError
Command "python setup.py egg_info" failed with error code 1 in /tmp/tmpoons7qgkbuild/opencv-python/

是在最新的linux(5.4.0 x64)系统上运行 pipenv install opencv-python命令的结果。

如何修复pip9.exceptions.InstallationError确保pip和setuptools的版本足以满足manylinux2014 wheels的要求。

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

解释
对我来说， python setup.py egg_info可能由于python轮子最近的变化而失败，因为 manylinux1 wheels根据 open-cv faq替换了 manylinux2014 wheels。
