為什么我安裝這個 opencv-python 的庫會報錯，但我安裝其他庫（比如：flask）就不會？

你的pip3 為什么運行在2.7的環境中？opencv已經不支持python2 了uj5u.com熱心網友回復：
我也不知道啊～你知道怎么改嗎？uj5u.com熱心網友回復：
Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained.大意是說python2.7不在維護了，叫你下載python3，你把現在的python卸了重裝

我安裝了 python 3.7 了，而且按道理 pip3 不是應該是運行 python3 的嗎？uj5u.com熱心網友回復：
需要配置pip默認使用的python版本https://jingyan.baidu.com/article/a17d5285daf7398099c8f251.html
