Command 'pm2' not found

Question

I recently cloned my nodejs express app on ec2 ubuntu instance. I ran npm install pm2 but it didn't have write permissions. So I ran

sudo chown _R $USER /usr/lib/node_modules

After that PM2 got installed but when I hit pm2 start app.js, it shows pm2 command not found. I have installed it globally locally but nothing works. What should I do? Check out the screenshot of ERROR

Answer 1

pm2 needs to be installed globally (on the server) to function correctly.

Try

sudo npm install -g pm2

Digital Ocean has an excellent tutorial on this.
