I ran into a quite similar issue.
In my case i fixed it by manually installing npm install electron --save-dev inside the projects folder.
And after that setting the directory / postinstall line in the package.json file:
from
postinstall": "node_modules/.bin/electron-rebuild -e ../../node_modules/electron
to
postinstall": "node_modules/.bin/electron-rebuild -e node_modules/electron
