How to install numpy on windows using pip install

Question

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

Installing extension modules can be an issue with pip. This is why conda exists. conda is an open-source BSD-licensed cross-platform package manager. It can easily install NumPy.

Two options:

Install Anaconda here
Install Miniconda here and then go to a command-line and type conda install numpy (make sure your PATH includes the location conda was installed to).
