My code is entered as follows

pip install numpy

And I got a chunk of error message as follows. (FYI, pip itself is working fine I suppose since I can install other packages like virtualenv, algopy using pip without getting any error)

  • One of the lines says `error: Unable to find vcvarsall.bat`. You might want to take a look at this question: https://stackoverflow.com/questions/2817869/error-unable-to-find-vcvarsall-bat or this one (specifically for numpy on windows): https://stackoverflow.com/questions/18730486/python-installation-error-numpy-package – Neitsa Jan 15 '16 at 01:17
  • Download the numpy wheel with intel MKL for your own needs [from here](http://www.lfd.uci.edu/~gohlke/pythonlibs/) and install the .whl file with pip (just replace `numpy` with the file name in your first command) – percusse Jan 15 '16 at 09:43
  • @Neitsa@percusse Thanks you both, it worked (I guess the problem is just vcvarsall.bat). Just wonder if http://www.lfd.uci.edu/~gohlke/pythonlibs/ is constantly updating their packages. Also, is .whl file something like source file and what's the difference between .whl file and the file on Python website after all? Am I supposed to completely depend on this website to download everything I need without bothering Python website in the future? – Nicholas Jan 15 '16 at 15:28
  • A whl file is a file in the [wheel format](http://pythonwheels.com/). It allows the installation of a C extension without a compiler (because the compiled module ships in the whl file). It's easier on Windows where you don't necessarily have the right compiler. No you don't need to use that site for each package, but you'll probably need it if the packages requires a C extension though... – Neitsa Jan 16 '16 at 21:38
