  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:

报错的原因是有的包里已经装了依赖库six 1.4.1

4.解决报错的方法：sudo pip install Scrapy --ignore-installed six

5.然后命令行输入：scrapy,还是不行，会报错：

ImportError: cannot import name xmlrpc_client

解决方法见

但是首先的关闭mac的sip(System Integrity Protection 系统完整性保护),关闭步骤如下：

a、重启mac，按住Command +R键知道Apple大大的苹果logo出现，进入Recovery模式

b、点击Utilties->Terminal

c、在Terminal中输入:csrutil disable ，回车

d、重启mac

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

为了下次装环境，特意记录了下来。

 

安装完后，重新开启sip，只是输入的命令位:csrutil enable
