Can I change the version of npm my Glitch terminal uses?

[lostbearlabs]

I see lots of questions (including from me, and one in the FAQ) about changing the version of node that a project uses, but my search has not turned up anything about npm.

If I go to the terminal in my new project and run a command like npm test I get the message New major version of npm available! 7.20.6 -> 8.11.0. Is this something I can upgrade myself, or should I just wait for some kind of a system-wide upgrade?

FWIW, if I try to run the suggested command in the message, npm install -g [email protected], I get the following:

$ npm install -g [email protected]

Hi there - your project container uses the version of npm that comes installed with whatever version of Node your project is using. At the moment, that’s the only mechanism for changing npm versions that we support.

I’ll make sure to get this info into a Help Doc so folks understand this going forward!
