When attempting to run a local dev instance, I’m getting this after `bin/ember-cli -u`:
```plaintext
- building...
Build Error (TemplateCompiler) in raw-templates/badge-selector-autocomplete.hbr
ENOENT: no such file or directory, open '/tmp/broccoli-155704EZeLMQlFLy1Y/out-0004-template_compiler/raw-templates/badge-selector-autocomplete.js
```
I could have somehow broken things locally, but this hasn’t occured before.
It’s expecting a js file to go along with an `hbr` file?! Why would it do that?

OK solved!
I was attempting to use latest version of node (20.x) as I’d been told 16.x was out of date.
when I switched back to lts/hydrogen (18.x) it built fine again.
Things clearly don’t work with node 20.x yet (for me!)
Lesson learnt. :mortar_board:

That’s good to know. I’ve been seeing this warning but ignoring it:
`WARNING: Ember CLI v5.0.0 is not tested against Node v20.10.0. See "https://github.com/ember-cli/ember-cli/blob/master/docs/node-support.md" to find out which version of Node is best to use.`
I need Node `v20.10.0` for another app that’s running concurrently on my local machine. Installing [NVM](https://github.com/nvm-sh/nvm) seems to have resolved the issue:
`~/discourse$ nvm use 18.18.2`

Yeah `nvm` was far more straightforward to use on WSL2 than `n` which had all kinds of permission issues …
