1、安装home brew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2、安装pip

 不要用这个命令安装

sudo python get-pip.py

安装会报错

解决方法:

easy_install pip

3、安装Scrapy

sudo pip install Scrapy

但是会报错

Downloading attrs-16.0.0-py2.py3-none-any.whl

Installing collected packages: pyasn1, pyasn1-modules, attrs, service-identity, six, w3lib, Twisted, lxml, cssselect, parsel, PyDispatcher, queuelib, 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:

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

http://stackoverflow.com/questions/30964836/scrapy-throws-importerror-cannot-import-name-xmlrpc-client

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
