pip ERROR cound not find a versi

树莓派 pip 安装 opencv 出问题

pip3 install opencv-python

ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: none)
ERROR: No matching distribution found for opencv-python

经过查阅也没有找到解决方案, 换源没有用. 没有尝试直接卸载python, 因为有很多库安装起来麻烦.

可以使用apt来安装

sudo apt install python-opencv 

sudo apt install python3-opencv

分别安装两个版本.
