Anaconda 错误：无法从 pyproj 导入名称 Transformer

Question

I try to install Transformer from pyproj and get the message "cannot import name". I installed pyproy using Anaconda Navigator. There it tells me I have version 1.9.6. (newest update). I found a thread about same issue but it didn't help me ( cannot import name Transformer from pyproj ). I checked pyproj-Documentation and installed via terminal conda install -c conda-forge proj-datumgrid-europe proj-datumgrid-north-america proj-datumgrid-oceania proj-datumgrid-world .

Not sure if that's the right thing to do. I'm a noob.-. help is appreciated.

ImportError                               Traceback (most recent call last)

ImportError: cannot import name 'Transformer' from 'pyproj' (/Users/vob/opt/anaconda3/envs/geopandas/lib/python3.8/site-packages/pyproj/__init__.py)

The latest version of pyproj is 3.3 at the moment. To update, recommend looking at pyproj installation instructions: https://pyproj4.github.io/pyproj/stable/installation.html

Here is a snippet:

conda config --prepend channels conda-forge
conda config --set channel_priority strict
conda create -n pyproj_env pyproj
conda activate pyproj_env
