报错：

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:
Traceback (most recent call last):

原因分析：

：Scrapy依赖six库，但是系统的six库比较老，安装scrapy需要卸载之后安装一个新的。但是Mac OS本身也依赖six，导致无法删除，因此没有办法安装Scrapy。

　解决的方式：使用virtualenv来安装。

1. sudo pip install virtualenv
2. virtualenv scrapyenv
3. cd scrapyenv
4. source bin/activate
5. pip install Scrapy　　

安装完成之后，安装如下包：

好了，可以使用scrapy startproject yourproject开始你的爬虫之旅了。

执行卸载和重装six的时候 not premitted

于是：

xcode-select --install

sudo pip install scrapy --ignore-installed six

然后错误：

ImportError:cannot import name xmlrpc_client
原因还是因为没有six

终端下执行

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

卸载掉six并重装，再次查看Scrapy版本，搞定。

如果执行第二条语句出错的话 就说明即便是sudo权限还是被拦截了

这时候：

重启电脑 进入 recovery mode （点击command＋R） 在左上角的终端中 输入：csrutil disable

成功！
