解决Mac安装scrapy失败的问题
今天打算弄个爬虫，想来想去打算用python弄一个。之前了解到scrapy这个库是个不错的选择，于是开始折腾。可惜第一步就挂了。
安装scrapy库就不成功：
Installingcollectedpackages:six,w3lib,parsel,pyasn1,pyasn1-modules,attrs,service-identity,scrapy Foundexistinginstallation:six1.4.1 DEPRECATION:Uninstallingadistutilsinstalledproject(six)hasbeendeprecatedandwillberemovedinafutureversion.Thisisduetothefactthatuninstallingadistutilsprojectwillonlypartiallyuninstalltheproject.

果断google+stackoverflow。
结论是：

brewinstallpython
原因是旧的python版本在新的mac系统上有些问题。升级一下就好了。
