Install nodejs_24 on NixOS running on WSL-2

[mwoodpatrick]

I'm using flakes to control my NixPS configuration running on WSL-2 my state version is 25.05.

I can install nodejs_23 without issue but when I try to install nodejs_24 I get:

error: undefined variable 'nodejs_24'

The wen page:

nodejs_24

Shows the package should exist

What am I doing wrong? How to fix this?

you say that your stateVersion is 25.05 - that doesn't necessarily mean you're running 25.05. you should not change the stateVersion from when the machine was installed.

that you can install nodejs_23 suggests that you are not running 25.05 as it was removed for 25.05 release to default to nodejs_24
