Error finding empirica with fresh clone and build

[shapeseas]

When doing a fresh clone of deliberation-empirica and running npm run build in the root folder, empirica: not found. Either the build script is not working or I needed to do another step to get the newest empirica on my machine. In the latter case, documentation could be clearer.

Full response:

 deliberation-empirica@1.0.0 build
