how can I install numpy on pypy on my 64 bit computer running Windows 64 bit?

问题

hardware/software: Machine 64 AMD processor running 64 bit windows

I have a computationally heavy program that I wish to speed up by using Pypy. I have installed pypy and also installed Microsoft Visual Studio and Microsoft Visual C++ Build Tools.

My python program uses Numpy so I tried to install numpy on pypy using the following

pypy3 - m pip install numpy

The error message I get says:

error: Microsoft Visual C++ 14.1 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

However I have already installed Microsoft Visual C++ Build Tools? I reinstalled it several times but got the same results.

How can I successfully install numpy for pypy3?

command used :

pypy3 - m pip install numpy

I expect numpy to be installed on PYPY but the results I get are:

  c:\pypy\pypy3.6-v7.0.0-win32\lib-python\3\distutils\dist.py:261: UserWarning: Unknown distribution option: 'define_macros'

You might need to run pypy3 -mpip install --upgrade setuptools to get a version of setuptools that can find your build tools. You can also pypy3 to use your version of the build tools by running pypy3 from a developer command prompt, be sure to choose the 32-bit version of the developer tools (pypy on windows is not available in a 64-bit version)
