Python 3, How to set Visual Studio C++ 2015 compiler?


I have installed Python 3.6 64bit version for my Windows 10 PC. I also have Visual Studio 2015 which has these folders: Visual studio 2015 folder

Some python libs, like pycrypto requires C++ compilation in order to be installed.

Now when I try to install pycrypto it throws me that kind of error:

warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.
building 'Crypto.Random.OSRNG.winrandom' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

Command "d:\python36\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\MrD\\AppData\\Local\\Temp\\pip-build-rzwqmfpp\\pycrypto\\setup.py';f=getattr(tokenize, 'ope

ll-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\MrD\AppData\Local\Temp\pip-build-rzwqmfpp\pycrypto\

How to make python3 to be able to use my VS 2015 C++ compiler?

========= UPDATE ============

I was able to install Common C++ tools for Visual Studio. Now my VC folder looks like this: after installation

Now when I try to install my pycrypto I get these errors:

It says that it has syntax errors?!! Did I miss something?


Solution

  • I think I have found solution for my own question. More like I have found the way how to evade this problem.

    The method is to install pycryptodome instead of pycrypto. According to their description it is fully compatible with pycrypto and it installed without any conflicts.
