PyCrypto installation error (vc\\cl.exe fails no matter what)

I am trying to install pyCrypto (by pip3 install pycrypto) , and I keep getting this error :

  Failed building wheel for pycrypto
  Running setup.py clean for pycrypto

Installation goes well until :

    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\cl.exe' failed with exit status 2

I have searched every topic I could find regarding this exact error , both on this website and many other , but I could not find a fitting solution. (please , don't link me existing threads from this website)

Some things worth mentioning : I have tried setting up the env. variables , it didn't help.

I have also tried running vcvarsall.bat (inside VC) , as many have suggested. No effect.

Finally , I have tried reinstalling visual studio. 0 effect as well.

Any ideas ?

I found the solution : After following the advice of Dave (from comments), I encountered a new error , which I then solved by following this thread Python, installing clarifai --> VS14.0 link.exe failed with exit status 1158

This is the solution provided in this blog post

Edit the file inttypes.h and add just before the line of the error:

#define intmax_t long long
#define uintmax_t unsigned long long

Also, the solution provided in this StackOverflow question by @user1602 seems better, since it doesn't involve changing files in Windows SDK:

A workaround for Microsoft VC compiler is to force include stdint.h via OS environment variable CL:

Open command prompt

Setup VC environment by runing vcvars*.bat (choose file name depending on VC version and architecture)

set CL=-FI"Full-Path\stdint.h" (use real value for Full-Path for the environment)

pip install pycrypto
