Is there a system-level package manager for Node instances on the App Platform?

I am attempting to deploy a Node app on the App Platform (the jQuery UI download builder at

The app requires a system library to be installed, xsltproc. I’ve attempted adding sudo apt install xsltproc as a build command, though it fails for lack of privileges.
