pm2 issue

[wetherallCode]

I'm following the instructions for using pm2 and when I enter pm2 startup ubuntu, I get this:

pm2 startup ubuntu
[PM2] Init System found: systemd

PM2 detected systemd but you precised ubuntu
Please verify that your choice is indeed your init system
If you arent sure, just run : pm2 startup

[PM2] You have to run this command as root. Execute the following command:
sudo env PATH=$PATH:/home/deploy/.nvm/versions/node/v8.1.4/bin /home/deploy/.nvm/versions/node/v8.1.4/lib/node_modules/pm2/bin/pm2 startup ubuntu -u deploy --hp /home/deploy
deploy@ubuntu-512mb-nyc1-01:~$ sudo env PATH=$PATH:/home/deploy/.nvm/versions/node/v8.1.4/bin /home/deploy/.nvm/versions/node/v8.1.4/lib/node_modules/pm2/bin/pm2 startup ubuntu -u deploy --hp /home/deploy
[sudo] password for deploy:
deploy is not in the sudoers file. This incident will be reported.

What should I do?
