DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

根据日志我认为是因为six模块试图用
sudo pip install haxor-news --upgrade --ignore-installed six
已安装，但在尝试正确安装测试时，我输入scrapy并面对

我发现有关此问题的问题，并通过
解决sudo rm -rf /Library/Python/2.7/site-packages/six*
sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six*
sudo pip install six
但面对<{p}的sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six
