Can't find msguniq. Make sure you have GNU gettext tools 0.15 or newer installed.

在设置django国际化时 执行命令
python manage.py makemessages -l zh_hans
报错，
CommandError: Can’t find msguniq. Make sure you have GNU gettext tools 0.15 or newer installed.

MAC ,django1.9

解决方法：
1、Install Homebrew : /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
2、Install GNU gettext : brew install gettext
3、Create symlink : brew link gettext –force

第一步可以忽略，执行brew install gettext时会自动安装，第三步一定要执行，不执行第三步还会报错，切记！
