brew link sip出错

brew安装sip时出现的问题：

$ brew install sipError: The `brew link` step did not complete successfullyThe formula built, but is not symlinked into /usr/localCould not symlink include/sip.h/usr/local/include is not writable.You can try again using:  brew link sip$ brew link sipLinking /usr/local/Cellar/sip/4.19.5... Error: Could not symlink include/sip.h/usr/local/include is not writable.

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

解决：

$ sudo mkdir /usr/local/include$ sudo chown $(whoami):admin /usr/local/include

成功：

$ brew link sipLinking /usr/local/Cellar/sip/4.19.5... 10 symlinks created
