修复损坏的python opencv安装

Question

似乎我破坏了opencv python安装： pip3 freeze | grep opencv没有显示任何内容，在import cv2上我得到错误：

python3

删除/usr/local/lib/python3.7/site-packages/cv2.cpython-37m-darwin.so是否安全

Answer 1

rm -f /usr/local/lib/python3.7/site-packages/cv2.cpython-37m-darwin.so

# reinstall opencv from source with python support

# Installing tbb via brew fixed the problem:

brew install tbb
