error: No compatible architectures found for build

[MaxOrelus]

I'm trying to build a node application rpm using your npm package. I've filled out all the options concerning arch with x86_64 as that's the platform I'm currently running. I get the following error when I run the npm start.

[root@unknown0800277ccd0f node-app]# uname -m
x86_64

[root@unknown0800277ccd0f node-app]# npm start

OS I'm build on.

platform:linux
distro:CentOS Linux
release:7
codename:Core
kernel:3.10.0-957.12.2.el7.x86_64
arch:x64
hostname:unknown0800277ccd0f.attlocal.net

logofile:centos
serial:f5438d6c4f924545873e64ebe3d743a4
build:N/A
servicepack:N/A

Also, I noticed that the keepTemp option has no logic. Whether I set it or not, it still keeps the temp directory. Not sure if that's happening because the builds are failing before it can complete.
