#6150·pm2

PM2 module installation should support other package managers

Author: hyunbinseoCreated Sep 5, 2026Updated Sep 5, 2026

bash

node -v  # v24.20.0
pnpm -v  # 12.3.1
npm -v   # NOT FOUND — zsh: npm: 명령을 찾을 수 없습니다...
pm2 -v   # 7.0.4

pm2 install pm2-logrotate

The error happens in /pm2/lib/API/Modules/NPM.js:

[PM2][Module] Calling [NPM] to install pm2-logrotate ...

}

Node.js v24.20.0

npm might not exist in the system, so respecting the package manager used to install PM2 would be nice.

Installing a Node.js runtime via node@runtime:<version> (including pnpm env use and pnpm runtime set node) no longer extracts the bundled npm, npx, and corepack from the Node.js archive.
