install error using Napari GUI

[JoeBeton]

I have been having some problems installing the latest version of blik using both the napari point&click installer and pip.

To reproduce (for me):

$ python -m pip install --upgrade blik 
$ npe2 validate blik 
🅇 Invalid! 1 validation error for PackageMetadata
metadata_version
  unexpected value; permitted: '1.0', '1.1', '1.2', '2.0', '2.1', '2.2' (type=value_error.const; given=2.3; permitted=('1.0', '1.1', '1.2', '2.0', '2.1', '2.2'))

I get an almost identical error if I use the napari point and click installer within the GUI.

I managed to get around this by installing blik version 0.6.1, i.e.:

$ python -m pip install "blik==0.6.2" 
$ npe2 validate blik 
✔ Manifest for 'blik' valid!

System info:

• Installed napari within conda environment
• Python version: Python 3.10.13
• pip version: pip 24.0
• napari version: 0.4.19.post1
• conda version: 24.1.1
• OS: Ubuntu 20.04

Let me know if there's any more info that can be helpful and thanks for the great plugin!

Hi @JoeBeton! Can you post the output of napari --info? I tried installing napari and blik in a new env without anything special and it works for me, so there must be something else afoot :P

oh and probably more interesting here's the output with blik==0.6.13 installed:

If I downgrade to npe2==0.7.4 like you have, I also get the same error. I'm not sure why you ended up with a mismatch here, but pip install npe2 -U should hopefully fix your issue!

[brisvag]

@czaki is this something we might need to fix on npe2/napari side?

[Czaki]

I think that all responses are in this PR https://github.com/napari/npe2/pull/344

Okay great I'll try that, thanks!
