Error: Expected in: flat namespace occuring out of the blue

Hi. When I download pyproj (MAC M1 chip, Big Sur 11.0.1) on python in a VENV folder it works originally then always seems to come up with the following error:

Traceback (most recent call last):

Really frustrating me, any ideas. Thanks. I have the latest proj downloaded with brew and pyproj via pip

Yes, I also wondered about that.

So next step would be to ignore the wheel, right?

pip install pyproj --no-binary :all:

I’m getting a weird ascii decode error within pip, so I disable PEP517 for legacy build behaviour:

$ pip install pyproj --no-binary :all: --no-use-pep517
Collecting pyproj

Skipping wheel build for pyproj, due to binaries being disabled for it.

However I’m hitting the same issue as before: ImportError ... pyproj/_network.pypy39-pp73-darwin.so, 0x0006): symbol not found in flat namespace '_proj_context_is_network_enabled'

Any solution to this? I am running into same issue with Mac M1 Monterey
