install scrapy on win 7 (64
I'm trying to install scrapy for python2.6, but it seems not going well. Here is the packages installed:
G:Python26Scripts>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
I also got iconv and zlib. And this is the log when installing scrapy with pip. I don't know what I should do next, am I missing sth? Need instructions, thank you.
win 7 64-bit, Visual C++ installed
C:Usersd>pip install scrapy

ImportError: DLL load failed: %1 is not a valid Win32 application
You need to follow the instructions here (also listed above).
The specific DLL error listed in the question is due (at least in my case) to installing the 32 bit OpenSSL with 64 bit everything else. After I installed the correct OpenSSL (and, incidentally, had to uninstall all of the packages in the link above and start over- order matters for the dependency msi installers), scrapy is working fine on python27, windows7, 64 bit.
请阅读本指南以在Windows 7上安装scrapy。egenix-pyopenssl被列为必需软件包，并且安装pywin32也可能有所帮助。
In my case I did upgrade python which caused this problem.
a simple scrapy upgrade did the trick
pip install --upgrade Scrapy
Also install correct version of pywin : http://doc.scrapy.org/en/latest/intro/install.html#windows
