pyproj - 导入错误：无法导入名称“_datadir”

Question

安装后pyproj，geopandas导入后者时出现错误：

!conda install --offline -c conda-forge geopandas-0.7.0-py_1.tar.bz2
!conda install --offline -c conda-forge pyproj-2.6.0-py38hff69d4a_0.tar.bz2
import geopandas

ImportError: cannot import name '_datadir'

我尝试使用这个答案，在使用 pyinstaller 将 .py 制作为 .exe但没有成功后，出现错误“没有名为 'pyproj._datadir' 的模块” ：

from pyproj import _datadir, datadir
---------------------------------------------------------------------------

ImportError: cannot import name '_datadir'

我正在使用 Windows 8.1 并且

conda version : 4.5.4
conda-build version : 3.10.5
python version : 3.6.5.final.0

有什么解决方案/解决方法吗？

我也有同样的问题。安装proj后解决

conda install --offline proj-7.2.0-he47e99f_1.tar.bz2
