[eleanorjboyd]

huh this is a very interesting bug! @karthiknadig any ideas?

[dalito]

Maybe its related to this: python/pymanager#160

[Triquetra]

@dalito I do have pymanager.exe installed, and I do use uv to manage virtual environments and packages. So, maybe that issue is related?

[eleanorjboyd]

Are you getting that popup in your terminal if you try and activate the environment or when you do uv python list manual?

[Triquetra]

Yes, uv python list causes the doc site to open in my browser.

[dalito]

So updating pymanager should fix it for you too.

[eleanorjboyd]

ok great- thank you or trying that and I will defer to the upstream issue for the fix

[GWRIGHT-PAN]

I have this same issue, I don't use uv though. Is the solution still to update pymanager?
