在win 7(64位)上安装scrapy

Question

我正在尝试为python2.6安装scrapy,但似乎进展不顺利.这是安装的包:

G:\Python26\Scripts>pip freeze
Scrapy==0.16.4
Twisted==12.3.0
libxml2-python==2.7.7
lxml==2.3.6
pyopenssl==0.13
w3lib==1.2
zope.interface==3.8.0

我也有iconv和zlib.这是用pip安装scrapy时的日志.我不知道接下来应该做什么,我不记得了吗？需要说明,谢谢.

win 7 64位,安装了Visual C++

阅读本指南以在 Windows 7 上安装 scrapy。egenix-pyopenssl 被列为必需包，另外安装 pywin32 也可能有所帮助。
