Description

When using the new "poetry env activate" command, I get the following output:

Expected output after running "poetry env use 3.12" at least once:

The issue I take here is that on Windows PowerShell, the env use command is not necessary. Here, poetry Install is enough.
Maybe it is expected behavior, but it is not consistent across platforms.

Workarounds

Run "poetry env use" beforehand.
