[python] How to install numpy on windows using pip install?

I want to install numpy using pip install numpy command but i get follwing error:

RuntimeError: Broken toolchain: cannot link a simple C program

I'm using windows 7 32bit, python 2.7.9, pip 6.1.1 and some MSVC compiler. I think it uses compiler from Visual C++ 2010 Express, but actually I'm not sure which one because I have several visual studio installations.

I know that there are prebuilt packages for windows but I want to figure out if there is some way to do it just by typing pip install numpy?

Edit: I think that there could be other packages which must be compiled before usage, so it's not only about numpy. I want to solve the problem with my compiler so I could easily install any other similar package without necessity to search for prebuilt packages (and hope that there are some at all)

As of March 2016, pip install numpy works on Windows without a Fortran compiler. See here.

pip install scipy still tries to use a compiler.

July 2018: mojoken reports pip install scipy working on Windows without a Fortran compiler.

I had the same problem. I decided in a very unexpected way. Just opened the command line as an administrator. And then typed:

pip install numpy

Frustratingly the Numpy package published to PyPI won't install on most Windows computers https://github.com/numpy/numpy/issues/5479

Instead:

1. Download the Numpy wheel for your Python version from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
2. Install it from the command line pip install numpy-1.10.2+mkl-cp35-none-win_amd64.whl

Check installation of python 2.7 than install/reinstall pip which described here than open command line and write

pip install numpy

or

pip install scipy

if already installed try this

pip install -U numpy

First go through this link https://www.python.org/downloads/ to download python 3.6.1 or 2.7.13 either of your choice.I preferred to use python 2.7 or 3.4.4 .now after installation go to the folder name python27/python34 then click on script now here open the command prompt by left click ad run as administration. After the command prompt appear write their "pip install numpy" this will install the numpy latest version and installing it will show success comment that's all. Similarly matplotlib can be install by just typing "pip install matplotlip". And now if you want to download scipy then just write "pip install scipy" and if it doesn't work then you need to download python scipy from the link https://sourceforge.net/projects/scipy/ and install it.

py -m pip install numpy

Worked for me!

Install miniconda (here)

After installed, open Anaconda Prompt (search this in Start Menu)

Write:

pip install numpy

After installed, test:

import numpy as np
