Development Questions/Chat

I've followed the development steps per the readme, but not able to get a running app yet. The first \electron window shows:

[nodemon] starting `tsc --project ./tsconfig.dev.json && electron . || exit 1`
src/electron.ts:33:24 - error TS2307: Cannot find module 'forcefocus' or its corresponding type declarations. 
33 import forceFocus from 'forcefocus';
~~~~~~~~~~~~ 
Found 1 error. 
[nodemon] app crashed - waiting for file changes before starting...

Then the second root window asks if I want to start, then I allow changing port, then outputs this:

? Something is already running on port 3000.
Would you like to run the app on another port instead? Yes

What am I doing wrong?
