InvalidToolsetDefinitionException when installing npm libpq on Windows

I'm using a VM to get a local dev environment to test my electron app on a windows machine.

I've installed postgres, git, node, npm visual studio, etc on my windows computer. I'm now trying to npm install in an existing project, and I'm getting this error:

C:\Users\nprince\nacho\app\node_modules\libpq>if not defined npm_config_node_gyp (node "C:\Users\nprince\AppData\Roaming\npm\node_modules\npm\bin\node-gyp-bin\\..\..\node_modules\node-gyp\bin\node-gyp.js" rebuild )  else (node "" rebuild )
