Answer 1 · 2022-03-22T14:43:39.000Z

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

Answer 2 · 2022-03-22T14:58:23.000Z

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

Answer 3 · 2022-03-22T15:43:19.000Z

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

I will update this post as I discover more.

Answer 4 · 2022-03-25T17:23:41.000Z

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.

Answer 5 · 2022-03-31T14:28:57.000Z

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

Answer 6 · 2022-03-31T14:43:00.000Z

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

Answer 7 · 2022-04-01T06:57:05.000Z

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.

Answer 8 · 2022-04-05T03:53:21.000Z

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?

Answer 9 · 2022-04-12T22:27:48.000Z

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

Answer 10 · 2022-04-16T19:39:45.000Z

so the issue is with C drive or something with permissions... dunno

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

Answer 11 · 2022-04-16T20:04:09.000Z

@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 🤡
