解决mac下brew link python3出错brew Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks

• $brew install python3

提示错误

$ brew install python3 Warning: python3 3.6.3 is already installed, it's just not linked. You can use `brew link python3` to link this version. $ brew link python3 Linking /usr/local/Cellar/python3/3.6.3... Error: Permission denied @ dir_s_mkdir

发现/usr/local/下没有路径/usr/local/Frameworks
需要新建该路径，并修改权限

解决：

$ sudo chown $(whoami):admin /usr/local/Frameworks

成功：

Linking /usr/local/Cellar/python3/3.6.3... 1 symlinks created
