Scrapy安转遇到问题

最近尝试使用Scrapy进行数据抓取，并尝试在windows7 64位系统上安装scrapy，下面总结记录遇到两个问题和解决方法：
 
scrapy官网的地址为：http://scrapy.org/
1、首先按照官网的说明，直接pip安装scrapy，报以下错误，提示缺少VC++9.0，报错信息有给出具体的说明和解决方法。
>>pip install scrapy
error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27
解决方法：直接点击下载VCForPython27.msi，也直接访问下面的连接https://www.microsoft.com/en-us/download/details.aspx?id=44266
 
2、下载并安装VCForPython27.msi，然后再运行pip install scrapy，再次报错，提示找不到libxml2库。
>>pip install scrapy
c:\users\zjn3645\appdata\local\temp\xmlXPathInit7hkp2z.c(1) : fatal error C1083: Cannot open include file: 'libxml/xpath.h': No such file or directory
*********************************************************************************
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
*********************************************************************************
error: command 'C:\\Users\\zjn3645\\AppData\\Local\\Programs\\Common\\Microsoft\\Visual C++ for Python\\9.0\\VC\\Bin\\cl.exe' failed with exit status 2
 
解决方法：
使用easy_install安装lxml，然后再次安装pip install scrapy，成功~
>>easy_install lxml
 
3、scrapy安装完成，运行官网首页的样例报错，原因是缺少pywin32
>>scrapy runspider myspider.py
exceptions.ImportError: No module named win32api
2016-03-09 10:17:49 [twisted] CRITICAL:
 
解决方法：按照官方文档的说明安装
pywin32有32位和64位版本，
对于64位的windows 7，如果python环境变量已经正确安装，pywin32安装的时候仍然报找不到python的错误，尝试pywin32的32位版本。
 
总结：在安装和使用新的工具之前一定要先看看官方文档的说明，搞清楚安装和使用的前提条件！
4、关闭代理
默认使用代理，有些网页使用本地代理无法访问！
2016-03-09 15:18:21 [scrapy] DEBUG: Telnet console listening on 127.0.0.1:6023
2016-03-09 15:18:21 [scrapy] DEBUG: Crawled (403) <GET http://xxx.com.cn/xxx.html>
(referer: None)
2016-03-09 15:18:21 [scrapy] DEBUG: Ignoring response <403 http://xxx.com.cn/xxx.html>: HTTP status code is not handled or not allowed
关闭代理
修改settings.py如下
DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware': None,
}
 
 
 
 

1  解决办法 

手动安装 lxml包

 

去http://pypi.python.org/simple/lxml/，下载win7 x64的(注意下载对应你系统版本)：

https://pypi.python.org/packages/2.7/l/lxml/lxml-2.2.8.win-amd64-py2.7.exe#md5=cfcf7f07a5016a5934271cddde4bbcbe

然后重新打开cmd去pip install Scrapy，解决了此xml的问题了

 
 
 mac安装遇到问题：

You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
