Installation in python3.6 via pip fails in 64-bit Windows

[alexjfx]

The error is as follows:
cl : Command line error D8021 : invalid numeric argument '/Wno-error=declaration-after-statement' error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2

@alexjfx , Same error, did you solve this ?? I also tried with mingw32 and vs buildtool 2017, neither work.
