PM2 Start Appname Returning Error Cannot Find Modules in Ubuntu 16

Question

this is my first time using node js, and i found a complicated problem, i was thinking this issue because of yarn, so i've removed yarn package but still got the error in my log when i run sudo pm2 start myAppName

this is message i've got :

0|myAppName |     at tryModuleLoad (module.js:505:12)
0|myAppName |     at Function.Module._load (module.js:497:3)
0|myAppName |     at Function.Module.runMain (module.js:693:10)
0|myAppName |     at startup (bootstrap_node.js:191:16)
0|myAppName | Error: Cannot find module '/var/www/html/myAppName'

0|myAppName |     at startup (bootstrap_node.js:191:16)

the libraries and etc i believe is already installed in node_modules,

maybe you guys have a solution for my problem, should i use another command like pm2 ? or another else ?

please help, i will be appreciated

thanks anyway :)

Answer 1

now i get it, the problem is not about the path, in my case, i just execute command sudo pm2 update, and the error log in pm2 was gone.

thanks
