cannot install nexcsi

[IceNotCold]

My xubuntu 16.04 installed python 2.7 and python 3.8. When I excute "pin install nexcsi", it gets many errors:

ERROR: Exception:

so, what's wrong...

Seems like an error in pip,

Nexcsi needs python 3.8 or greater (https://github.com/nexmonster/nexcsi/blob/main/pyproject.toml), try installing with pip3.
