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 ```
