系统环境

• MacOS 11.4
• MacBook Pro M1
• homebrew
• python3.9

安装命令

brew install opencv@3 

注意：截至2021年8月，使用国内源安装会出现404错误。
解决方法：不使用国内源

export HOMEBREW_BOTTLE_DOMAIN='' 

具体原因参考：修复homebrew安装软件404问题

路径配置

安装后会输出如下内容：

==> opencv@3
opencv@3 is keg-only, which means it was not symlinked into /opt/homebrew,
because this is an alternate version of another formula.

If you need to have opencv@3 first in your PATH, run:
  echo 'export PATH="/opt/homebrew/opt/opencv@3/bin:$PATH"' >> ~/.zshrc

For compilers to find opencv@3 you may need to set:
  export LDFLAGS="-L/opt/homebrew/opt/opencv@3/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/opencv@3/include"

For pkg-config to find opencv@3 you may need to set:
  export PKG_CONFIG_PATH="/opt/homebrew/opt/opencv@3/lib/pkgconfig"

当我按照要求配置路径后，python中还是找不到cv2。

解决方法

检验

python3

>>> import cv2
>>>
