Bug summary
I am encountering an ImportError when attempting to use Matplotlib v3.8.0 in my Python package's tests, specifically when running them with pytest. This issue does not occur with older versions of Matplotlib, such as v3.7.3.
Code for reproduction
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):

When running the tests, I receive the following ImportError:

I expected my tests to run successfully with Matplotlib v3.8.0, just as they did with v3.7.3.
Additional information
-
Has this worked in earlier versions?
It is working in previous versions (eg, v3.7.3). -
Do you know why this bug is happening?
When running the following command to get the Matplotlib Backend:
import matplotlib; print(matplotlib.get_backend())I got the following error:
