build.sh script not producing any binaries

[lonnietc]

Brief Description: Trying to build binaries for Win64 and Linux64

Operating System (OS and version): Ubuntu20.04 (64-bit)

OpenBazaar version (shown on About OpenBazaar page in menu):

Hardware: AMD 64

Reproducible (Always / Almost Always / Sometimes / Rarely / Couldn't Reproduce): Always

To try and build Openbazaar-desktop binaries, I have installed nvm to use node v8.9.2, npm v5.2.0

Steps to reproduce:

1. issue "./build.sh win64" or ./build.sh linux64"

Observed Behavior:

There seems to be no output binaries in the ./dist directory and no sub-directories for each platform are created but the build script seems to run without error. Nothing is produced at all.

Expected Behavior:

I would expect that the ./dist directory has a "win64" directory with the executable and the "linux64" directory have the Linux binary so that I can start up and connect to an local openbazaar-go server that I have been able to compile up and run without any problems.
