win7下 scrapy的安装

学习自： http://scrapy-chs.readthedocs.io/zh_CN/0.24/intro/install.html

http://www.th7.cn/Program/Python/201505/447703.shtml

http://blog.csdn.net/mfcing/article/details/43449441

我的python已经是预先安装好的2.7版本的

原文中 pywin32的网址是：从 http://sourceforge.net/projects/pywin32/ 安装 pywin32

我的2.7  32位是这个网址

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/

建议按我的这个链接来 我找过两次没找到 今天这次找了30分钟终于找到了下载链接。。。。。之前下载的都是Readme.txt

首先第一个给的链接是用pip来安装的，我们安装库可以有几种方式

1：python XXX.py install

2：pip

3：easy_install

目前我接触的是这几种，

上面链接中第一个链接是安装pywin32之后安装pip通过pip进行安装的。

后面的是自己下载文件，通过exe文件以及easy_install和  python自己安装的。

 

下面我贴出来通过自己下载文件安装的帖子之后在我出错的地方标注我的错误之处，这样看帖子的人可以少犯错误进行安装scrapy了

一、 Scrapy简介

Scrapy is a fast high-level screen scraping and web crawling framework, used to crawl websites and extract structured data from their pages. It can be used for a wide range of purposes, from data mining to monitoring and automated testing.

官方主页： http://www.scrapy.org/

 

二、 安装Python2.7

官方主页：http://www.python.org/

下载地址：http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi

 

1) 安装Python

安装目录：D:\Python27

 

2) 添加环境变量

略System Properties -> Advanced -> Environment Variables - >System Variables -> Path -> Edit

 

3) 验证环境变量

T:\>set PathPath=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;D:\Rational\common;D:\Rational\ClearCase\bin;D:\Python27;D:\Python27\ScriptsPATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH

 

4) 验证Python

T:\>pythonPython 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32Type "help", "copyright", "credits" or "license" for more information.>>> exit()T:\>

 

 

三、 安装Twisted

Twisted is an event-driven networking engine written in Python and licensed under the open source

 

1) 安装setuptools

Download, build, install, upgrade, and uninstall Python packages -- easily!

官方主页：http://pypi.python.org/pypi/setuptools

下载地址：http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe

安装过程：(这里是exe文件)

 

2) 安装Zope.Interface

官方主页：http://pypi.python.org/pypi/zope.interface/

下载地址：http://pypi.python.org/packages/2.7/z/zope.interface/zope.interface-4.0.1-py2.7-win32.egg

安装过程：

T:\>d:D:\>cd D:\Python27\ScriptsD:\Python27\Scripts>easy_install.exe zope.interface-4.0.1-py2.7-win32.eggProcessing zope.interface-4.0.1-py2.7-win32.eggcreating d:\python27\lib\site-packages\zope.interface-4.0.1-py2.7-win32.eggExtracting zope.interface-4.0.1-py2.7-win32.egg to d:\python27\lib\site-packagesAdding zope.interface 4.0.1 to easy-install.pth fileInstalled d:\python27\lib\site-packages\zope.interface-4.0.1-py2.7-win32.eggProcessing dependencies for zope.interface==4.0.1Finished processing dependencies for zope.interface==4.0.1D:\Python27\Scripts>

(下面贴一段我的测试，正好上面链接的帖子里面也提到了，会有一个类型错误，不过可以使用库，那个错误貌似是easy_install里面的)

3) 安装Twisted

官方主页：http://twistedmatrix.com/trac/wiki/TwistedProject

下载地址：http://pypi.python.org/packages/2.7/T/Twisted/Twisted-12.1.0.win32-py2.7.msi

安装过程：(这里是exe文件)

 

四、 安装w3lib

官方主页：http://pypi.python.org/pypi/w3lib

下载地址： http://pypi.python.org/packages/source/w/w3lib/w3lib-1.2.tar.gz

解压过程：略

安装过程：

五、 安装libxml2

官方主页：http://users.skynet.be/sbi/libxml-python/http://pypi.python.org/pypi/pyOpenSSL

下载地址：http://users.skynet.be/sbi/libxml-python/binaries/libxml2-python-2.7.7.win32-py2.7.exe

安装过程：略(这里我开了翻墙打开的)

验证安装：

T:\>pythonPython 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32Type "help", "copyright", "credits" or "license" for more information.>>> import libxml2>>> 

 

 

六、 安装pyOpenSSL

官方主页：http://pypi.python.org/pypi/pyOpenSSL

下载地址：http://pypi.python.org/packages/2.7/p/pyOpenSSL/pyOpenSSL-0.13.winxp32-py2.7.msi

安装过程：(这里是exe文件)

验证安装：(下面是我的错误)

>>> import OpenSSL
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build\bdist.win32\egg\OpenSSL\__init__.py", line 8, in <module>
  File "build\bdist.win32\egg\OpenSSL\rand.py", line 10, in <module>
ImportError: No module named six

之后去找six包 提供了python2与3的差异性。

下载地址：

https://pypi.python.org/pypi/six/1.6.1

安装过程，进入文件夹下   python setup.py install

验证安装： import six

仍然缺： No module named cryptography.hazmat.bindings.openssl.binding

https://github.com/MattTW/HoneyAlarmServer/issues/1

https://bugs.archlinux.org/task/39388#comment120549

两篇文章我看到的是后面的版本可以解决这个问题，之后我就直接安装scrapy了 import scrapy 是可以的。之后我用下面那个方法

pip下载地址。不过一般自带的：

https://pypi.python.org/pypi/pip

将D:\Program Files\python27\Scripts  加入环境变量为了 让你在命令行里面随意使用pip而不用必须在他的文件夹下。

这个步骤成功的话(也就是在命令行下无论在哪个文件夹下 都可以使用pip了 之后进入到下载安装包的位置  pip install pyOpenSSL-16.2.0.tar.gz)

我下载的是这个包，之后pip帮你把所有的支持包也下载了。完成时候是这样的

Successfully installed asn1crypto-0.21.1 cffi-1.9.1 cryptography-1.8.1 enum34-1.

1.6 idna-2.5 ipaddress-1.0.18 packaging-16.8 pycparser-2.17 pyparsing-2.2.0

可以测试下，  import OpenSSL 没问题

pip install Scrapy-0.14.4.tar.gz

没问题和上一步骤一样的

之后就可以用了 scrapy

(不过我在深深的怀疑直接用pip  scrapy的支持会不会都下载下来~~而且  还是linux安装简单。。。)

七、 安装Scrapy

官方主页：http://scrapy.org/

下载地址：http://pypi.python.org/packages/source/S/Scrapy/Scrapy-0.14.4.tar.gz

解压过程：略

安装过程：

T:\Scrapy-0.14.4>python setup.py install……Installing easy_install-2.7-script.py script to D:\Python27\ScriptsInstalling easy_install-2.7.exe script to D:\Python27\ScriptsInstalling easy_install-2.7.exe.manifest script to D:\Python27\ScriptsUsing d:\python27\lib\site-packagesFinished processing dependencies for Scrapy==0.14.4T:\Scrapy-0.14.4>

 

验证安装

T:\>scrapy
Scrapy 0.14.4 - no active project


Usage:
  scrapy <command> [options] [args]


Available commands:
  fetch         Fetch a URL using the Scrapy downloader
  runspider     Run a self-contained spider (without creating a project)
  settings      Get settings values
  shell         Interactive scraping console
  startproject  Create new project
  version       Print Scrapy version
  view          Open URL in browser, as seen by Scrapy


Use "scrapy <command> -h" to see more info about a command


T:\>

另外，我自己在安装过程中遇到了问题。安装pyOpenSSL会出错：一个C语言头文件找不到，接着安装Scrapy也会报这个错误。

解决方案是下载Python的另一个安装工具PIP，安装PIP之后把C:\Python27\Scripts路径加入环境变量path，在控制台输入pip显示如下表示安装成功：

我们找到下载的pyOpenSSL文件位置，在那里打开cmd直接输入pip pyOpenSSL-0.14.tar.gz回车，接着就安装OK了。

然后用pip安装下Scrapy包，OK，搞定。
