i already try to delete node_module & package.json and run NPM install again, but it didnt work (Linux 4.19.0-16-cloud-amd64)

EDIT : solved with chown -R root /path/of/your/project

Answer 1

Alternative approach: use a non-root user.

NPM is trying really hard (see other answer for details) to not execute anything as root. So what about trying just that - not being root? You would do something like this

1. Add a local user (AMI guide), typically adduser john.doe --disabled-password
2. Login as the new user sudo -s -u john.doe
3. Clone your repo: git clone https://github.com/foo/bar; cd bar
4. Run NPM command npm i;npm run build:prod
