Cannot import name 'wraps' from 'astropy.utils.decorators'

Description

I can not import aplpy with astropy 5.0.4.

I installed astropy version 5.0.4 over conda: conda install -c anaconda astropy
Then, I installed aplpy version 2.0.3: conda install -c conda-forge aplpy
When I use ipython: import aplpy then here is the error:

I fixed this problem by modify in decorators.py file: /opt/anaconda3/lib/python3.9/site-packages/aplpy/decorators.py

#from astropy.utils.decorators import wraps
from functools import wraps #modify

[thatastroguy]

Ran into this same issue (but with astropy 5.2.2), except I first ran into the issue outlined in open issue #472 and had to first modify my aplpy core.py file. This issue then appeared. I can confirm your modification works and apply can be imported on my own system.

This has been fixed in #469 (in 2.1.0), but the current release is only installable via pip at this time.
