Recently I've came across some problems while installing scrapy with PIP. The problem is with installing cryptography.
Common solution is posted on StackOverflow, you should add libs before pip compile:
C:\> set LIB=C:\OpenSSL-Win32\lib;%LIB%
C:\> set INCLUDE=C:\OpenSSL-Win32\include;%INCLUDE%
C:\> pip install cryptography
But it didn't work for me, I still got error during compilation:
LINK : fatal error LNK1181: cannot open input file 'libeay32mt.lib'
The solution was quite ease, as it appears that C:\OpenSSL-Win32 (that I had) has subfolders in lib directory:
The solution is to simply add one more path to lib, that solves the issue:
C:\> set LIB=C:\OpenSSL-Win32\lib;C:\OpenSSL-Win32\lib\VC;%LIB%
