Updating dependencies
Resolving dependencies...

Because no versions of mpflash match >0.7.4,<0.7.5 || >0.7.5,<0.7.6 || >0.7.6,<0.7.7 || >0.7.7,<0.8.0
 and mpflash (0.7.7) depends on packaging (23.2), mpflash (>0.7.4,<0.7.5 || >0.7.5,<0.7.6 || >0.7.6,<0.8.0) requires packaging (23.2).
And because mpflash (0.7.6) depends on packaging (23.2)
 and mpflash (0.7.5) depends on packaging (23.2), mpflash (>0.7.4,<0.8.0) requires packaging (23.2).
And because mpflash (0.7.4) depends on packaging (23.2)
 and micropython-stubber (1.20.2) depends on mpflash (>=0.7.4,<0.8.0), micropython-stubber (1.20.2) requires packaging (23.2).
So, because micropy-cli depends on both packaging (==21.3) and micropython-stubber (==1.20.2), version solving failed.
