I Couldn't figure out how to fix the PORT issues with PM2 so i manually altered `react-scripts/scripts/start.js` to use another port. 


```
export NODE_PORT=3002 && sudo pm2 start node_modules/react-scripts/scripts/start.js --name "smashgg" --watch --interpreter "/home/pi/.nvm/versions/node/v12.18.2/bin/node"  -- export NODE_PORT=3002 PORT=3002 
```
