pyproj._datadir does not export expected C variable PJ_CATEGORY_DATUM_ENSEMBLE

Hi,

I am trying to configure my python environment on my new MacBook Pro with Apple Silicon M1 to run a project I am working on, but I am having troubles importing pyproj. When I try to run from pyproj import Proj I obtain the following error in return:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/homebrew/Caskroom/miniforge/base/envs/cbkenv/lib/python3.9/site-packages/pyproj/__init__.py", line 49, in <module>
    import pyproj.network
  File "/opt/homebrew/Caskroom/miniforge/base/envs/cbkenv/lib/python3.9/site-packages/pyproj/network.py", line 10, in <module>
    from pyproj._network import (  # noqa: F401
  File "pyproj/_network.pyx", line 1, in init pyproj._network
ImportError: pyproj._datadir does not export expected C variable PJ_CATEGORY_DATUM_ENSEMBLE

Installation method/steps

• Installation method (conda, pip wheel, from source, etc...)

I have been trying to install with conda but apparently the package cannot be found, the output of conda install -c Conda-forge pyproj is the following:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Current channels:

After that, I have managed to install pyproj using pip in my conda environment.

I have installed PROJ before installing pyproj with pip, using conda install PROJ
