I don't know why I encounter this error, when I run pm2 status:
kaitoSwift#kaito-MacBook-Pro school-sms2 % pm2 status
node:internal/fs/utils:344
throw err;
^

Answer 1

It is a permission error
If you are trying to use pm2 in ubuntu server on EC2 and getting error for error: EACCES and code :-13
Just follow these steps:
sudo su - to get to the root user permissions
then create an ecosystem.config.js file in the root folder:-
module.exports = {
apps : [{
name: "server",
script: "server.js"
}]
}
then write pm2 start server

Answer 2

For installing PM2, use this:
sudo npm install -g pm2
For the error with pm2 status it's the same try with:
sudo pm2 status
The error tell you that /Users/kaitoSwift/.pm2/pm2.log does not exists.

Answer 3

you need to run this in sudo and verify that you didn't have other process that run on the same port.
