Cannot import name 'sun' from 'sunrise'?

[water5]

I installed sunriseces, when run below: python meteogram_alderaan.py

rise this error:

Traceback (most recent call last): File "/home/mc3/prob_meteogram/meteogram_alderaan.py", line 13, in from sunrise import sun ImportError: cannot import name 'sun' from 'sunrise' (/home/mc3/.local/lib/python3.9/site-packages/sunrise.py)

And some packages seems not works or not available from PyPI:

ImportError: cannot import name 'droplet' from 'droplet'

wind_sock, lightning_bolt

How to install them?
