Can't install numpy – MS Visual C++ 14.1 is required. But it is installed
Question:
I am on Windows 10 using pypy3.6-v7.3.0. I am trying to install numpy with pip install numpy, but I keep getting the error: error: Microsoft Visual C++ 14.1 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/.
However I already have Visual Studio Community 2019 installed, and my C++ build tools are fully up to date.
Edit:
Here is the new error I am getting after installing build tools manually:

I am no longer seeing the original error anymore, I am always getting this no matter what now. I tried using pip install numpy, pip3 install numpy, and pypy -m pip install numpy. All give this same output.
Answers:
pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl
Try installing from wheel package directly.
-
If your build tools not answering to your problem, try to install build tools manually through this link.
-
After that you have to restart your PC or laptop.
-
Then try pip3 install numpy. In python 3.x versions we use pip3 not pip.
There is a clear distinctions between certain versions of Visual C++ Build Tools.
- Visual studio version 2015 build tools -> VC 14.0
- Visual studio version 2017 build tools -> VC 14.1
- Visual studio version 2019 build tools -> VC 14.2
Choose the build tools you need from the menu accordingly:
https://visualstudio.microsoft.com/vs/older-downloads/
You can also use chocolatey’s numpy package directly:
choco install numpy

I am no longer seeing the original error anymore, I am always getting this no matter what now. I tried using pip install numpy, pip3 install numpy, and pypy -m pip install numpy. All give this same output.
pip install numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl
Try installing from wheel package directly.
-
If your build tools not answering to your problem, try to install build tools manually through this link.
-
After that you have to restart your PC or laptop.
-
Then try
pip3 install numpy. In python 3.x versions we usepip3notpip.
There is a clear distinctions between certain versions of Visual C++ Build Tools.
- Visual studio version 2015 build tools -> VC 14.0
- Visual studio version 2017 build tools -> VC 14.1
- Visual studio version 2019 build tools -> VC 14.2
Choose the build tools you need from the menu accordingly:

You can also use chocolatey’s numpy package directly:
choco install numpy
