I'm very new to Python and programming world and has been going along with tutorials from newcoder.io This Here! I have been doing as per the instructions but when I try to install NumPy I get an error.

" error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27

But that's not enough, I tried to install VCForPython27.msi from the given link. But still, gets the same error.

Please Help!

Answer 1

I recommend installing the Anaconda distribution of Python. It contains more packages than you can dream of, including numpy of course: http://continuum.io/downloads

The installation is as straightforward as installing the usual Python, no matter what OS you are on.

Answer 2

A good solution is to download the wheel file which match your Python version here: unofficial python binaries

And then go to the folder where the .whl file is present using the command prompt and unpack the wheel file xxxxx.whl with:

>python -m pip install xxxxx.whl

This will install the library in the Lib\\site-packages folder, you can check it afterwards.
