Installing scrapy/pyopenssl in Windows' virtualenv

Question

I am trying to install scrapy on Windows XP (32bit) virtualenv:

pip install scrapy

The installer spits out this ambiguous error message:

error: Only found improper OpenSSL directories: ['E:\\cygwin', 'E:\\Program Files\\Git']

How should I configure openssl / pyOpenSSL to make pip work?

Answer 1

Apparently pyopenssl installation expects the binaries and libs to be laid out exactly as installed by OpenSSL windows binaries. Installing it from there (and not using cygwin's openssl for example), and adding the bin directory to the path solved this issue.
