安装Scrapy

1.用easy_install安装pip,pip 是对 easy_install的升级。

2.sudo pip install scrapy时会报错

#include "libxml/xmlversion.h"
    ^
    1 error generated.
    error: command ‘cc‘ failed with exit status 1

注：没有命令行开发工具 执行xcode-select --install ；而我有但是目录不对，要改变目录sudo xcode-select --switch /Applications/Xcode.app

3.解决办法

sudo C_INCLUDE_PATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2/libxml:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include pip install lxml

4.在执行sudo pip install scrapy，安装成功了。
