@UberMachine and others, kindly refer a post in ncube's thread.
I've posted instructions on how to your precompiled wheel files instead.
Just installing Build Tools may not work bcos some of the packages appear to be using a registry method of some sort to check if VC++ 2015 is installed and fails to interpret it completely.
Also note, Build tools 2017 , ie. 14.1.x is fully backward compatible with 2015 and in layman terms simply overwrites the old 2015.
In many cases 2017 will remove any VC++ 2015 entries that appear in control panel > programs and features.
Then it depends on one's tech level to sort the whole thing out, build tools 2015 doesnt even set path properly so post-installation problems will still persist.
A simple quickfix is to use wheel files. Just check the correct python version and win arch to install the correct one.
