Compilation error building pycrypto-2.6.1

[gbarakat]

Hello guys,

I am trying to install course builder on my Windows machine, and every time I got the same error message Exit 25

Compilation error building pycrypto-2.6.1. Please ensure a C
compiler is installed and functional on your system. On OS X, the most likely
cause of this problem is that you don't have the XCode Command Line Tools
installed. To fix this, run

$ xcode-select --install

and follow the instructions that appear, then re-run this command.
/usr/bin/bash: Exit 255.

I don't if is it possible to download XCode Command Line on Windows machine?

I have tried to download Pycrpto-2.6 Manually from http://www.voidspace.org.uk/python/modules.shtml#pycrypto but still not working, any ideas how to solve it?

Not sure if you're still having the issue - I ran into the same thing - I fixed it by installing gcc via the cygwin setup wizard setup-x86_64.exe - there is a stage where you choose which libraries to install with it and I simply selected the gcc and g++ modules.
I ended up then using the linux bash file to deploy course builder in cygwin rather than using the windows bat script

In my case, I resolved checking python version.
prompt> python -V
should be 2.7.x, not 3.x
