Issue with PM2 autostart...

[hawk13]

Hey I am getting an error when trying to configure the PM2 autostart. I ran the command they give:
pi@raspberrypi:~ $ sudo env PATH=$PATH:/usr/bin / usr/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi

Then it runs and I run the chmod script then when I try to run
pm2 start mm.sh

I get

 pi@raspberrypi:~ $ pm2 start mm.sh
events.js:160
  throw er; // Unhandled 'error' event
  ^

Error: connect EACCES /home/pi/.pm2/rpc.sock
at Object.exports._errnoException (util.js:1022:11)
at exports._exceptionWithHostPort (util.js:1045:20)
at PipeConnectWrap.afterConnect [as oncomplete] (net.js:1087:14)

Any suggestions?
