cwt always fails with the message AttributeError: 'pywt._extensions._pywt.Wavelet' object has no attribute 'comple x_cwt'

I installed pywavelts on an M2 mac using Python 3.11. Whenever I try to use cwt is fails with the message:

AttributeError: 'pywt._extensions._pywt.Wavelet' object has no attribute 'complex_cwt'

What is this about? Is there some problem with M2 macs?

I tried an installation using pip which gave version 1.7.0. I then tried the current github version which is 1.8.0.dev0

Any suggestions? In any case this isn't an acceptable error message.

To be more specific I tried cwt(bnds, 1, 'coif1') where bnds is a numpy array of np.float64. No matter what wavelet or scale I try I get the same error.
