Python 3 - Install pycrypto on Windows
I'm using Python 3.7 and Windows 10. 'pip install pycrypto' doesn't work with the following error:

The file include\pyport.h in Python installation directory does not have #include < stdint.h > anymore. This leaves intmax_t undefined.
A workaround for Microsoft VC compiler is to force include stdint.h via OS environment variable CL:
- Open command prompt, and Setup VC environment by runing vcvars*.bat (choose file name depending on VC version and architecture)
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC>vcvarsall.bat
- set CL=-FI"Full-Path\stdint.h" (use real value for Full-Path for the environment)
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC>set CL=-FI"%VCINSTALLDIR%\INCLUDE\stdint.h"
- then, try to install pycrypto again:
(pyramid) C:\Projects\Pyramid>pip install pycrypto Collecting pycrypto Using cached https://files.pythonhosted.org/packages/60/db/645aa9af249f059cc3a368b118de33889219e0362141e75d4eaf6f80f163/pycrypto-2.6.1.tar.gz Installing collected packages: pycrypto Running setup.py install for pycrypto ... done Successfully installed pycrypto-2.6.1
Another option that I'll try in future is to use PyCryptodome instead of pycrypto. pycrypto is discontinued and is no longer actively supported. PyCryptodome exposes almost the same API as pycrypto (source).
