顺利的话,一句命令搞定:
sudo pip install Scrapy
OSX还是需要额外一些包或升级的,包括:

cssselect, queuelib, six, w3lib, lxml, Twisted, characteristic, pyasn1, pyasn1-modules, service-identity

幸运的是pip或者easy_install 可以自动为你安装,但是其中的问题:

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:

OSError: [Errno 1] Operation not permitted: ‘/tmp/pip-qeBchm-uninstall/System/Library/Frameworks/Python.framework/
Versions/2.7/Extras/lib/python/six-1.4.1-py2.7.egg-info’

python

显然升级six是出错了,使用sudo
pip install six --upgrade 或者 pip uninstall six
都会遇到同样的错误。无论什么用户,多大权限。想必下载包安装也会同样问题。我只能这么认为:这都是pip的错。
好吧,那就easy_install试试吧。

sudo easy_install –upgrade six

继续使用easy_install 安装Scarpy吧:…

sudo easy_install Scrapy

看起来挺顺利..
可是….

In file included from src/lxml/lxml.etree.c:323:
src/lxml/includes/etree_defs.h:14:10: fatal error: ‘libxml/xmlversion.h’ file not found
#include “libxml/xmlversion.h”

看来libxml2 需要额外安装的

xcode-select --install

以下就顺利完成安装

sudo pip install Scrapy
OR
sudo pip easy_install Scrapy

One thought on “Install Scrapy on OSX|mac OSX 上安装Scrapy[SYN:gejoin.com]

  1. Really nice icons, useable and apicerpated, but I was surprised to see a complete void of Office Suite icons. Nothing for Word, Excel, PowerPoint, Outlook, etc.
