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：

Installing collected packages: six, w3lib, parsel, pyasn1, pyasn1-modules, attrs, service-identity, scrapy
 Found existing installation: six 1.4.1
 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.
 Uninstalling six-1.4.1:
Exception:

 os.chflags(dst, st.st_flags)

果断google+stackoverflow。

结论是：

brew install python

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。
