You are using NodeJS Version 17, which may be the cause of this error. It's working fine for me using NodeJS 16.

I'm not seeing this on Node 17.7.2. It works fine for me.

After further debugging, the issue is somehow related to running from a mapped network drive.

I will update this post as I discover more.

I'm having this issue as well. Running node 17 on windows 10. No mapped drives are used in this project. I do not have any mapped drives.

I'm having this issue as well. Running node 16.13.2 on windows 10. No mapped drive.

I've just tested this again on a fresh Windows 10 sandbox, Node 16.13.2, and cannot reproduce it.

I can confirm it works in sandbox.
I can fix that problem if i start "npm run dev" with admin access rights. No idea why.

Maybe it's related to rollup/rollup#4439. Can you check if your path has a different casing between the terminal and the file system?

fresh install, step by step from the site instructions, what's happening?

well... it did install on a second drive and it somehow works
so the issue is with C drive or something with permissions... dunno

edit: managed to install it on C: but strangely works only from deeply nested folders

I tried, and it fails with this error on both C, D, etc. I couldn't find such a place where it works.

@jasonlyu123 Yes, that's it. As soon as I changed c:\sources\... for C:\sources\... in my terminal, it started to work.
This is just an insanely stupid bug 🤡
