Please make sure you followed the requirements.
Using this method, will install the bot as a service. I still recomend using docker, but this method is here if you want to.
To install this app as a service, just run:
# this will install the packages forever and forever-service
# sudo is required to access the systemctl command
sudo yarn run install-service
And to remove the service:
# this will remove the service
sudo yarn run remove-service
# this will not remove forever and forever-service, you need to do that manually using
sudo yarn remove -g forever forever-service
