Hello @shaliniv37

You can try the following command

  1. npm install pm2 -g && pm2 update

pm2 update is necessary in order to refresh the PM2 daemon.

Hi @shaliniv37,

There is no need to install pm2 with npm install you can just use apt install pm2.

Here is an article that could help you configure a NodeJS environment with PM2:
