安裝命令
brew install opencv@3
注意：截至2021年8月，使用國內源安裝會出現404錯誤，
解決方法：不使用國內源
export HOMEBREW_BOTTLE_DOMAIN=''
具體原因參考：修復homebrew安裝軟體404問題
路徑配置
安裝后會輸出如下內容：
==> 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"
當我按照要求配置路徑后，python中還是找不到cv2，
解決方法
檢驗
python3
>>> import cv2
>>>
