pm2: not found

Hello. I deployed the project to the aws ec2. It gives this error when running. I tried a few things but no results. how do i solve this?

```
node-app-prod | $ pm2 start ecosystem.config.json --no-daemon
node-app-prod | /bin/sh: pm2: not found
node-app-prod | error Command failed with exit code 127.
```

Start with the deployment command in ecosystem.config.json and reproduce it on the AWS EC2 environment. Check how the project makes pm2 available to the shell; done when `pm2 start ecosystem.config.json --no-daemon` runs without the `/bin/sh: pm2: not found` error.
