I want to install parquet for python using pip within an Anaconda 2 installation on Windows 10.
While installing I ran into the error that is described here, the installer can't find snappy-c.h.
There is no mention on how to install this on Windows in the answers.
I downloaded the Snappy library from http://google.github.io/snappy/ and now I'm stuck.
From my error message I would have assumed that the header files need to be in C:\Users\...\AppData\Local\Continuum\Anaconda2\include, but in the downlaoded archive header and library files are just all in the same folder.
How do I install these properly in the Anaconda folder?

After a really long and frustrating time trying different methods to get the C files working, I found this site:
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Where C. Gohlke has kindly compiled and uploaded the files for us windows users.
Just download the version you need based on your system and python version. I am using 64bits and python 3.6, so I used the following command from my download folder:
pip install python_snappy-0.5-cp36-cp36m-win_amd64.whl
It worked like a charm :)
