python - ModuleNotFoundError : No module named 'pyproj.crs'

Question

I tried to import pyproj, and this error occurred.

import pyproj
Traceback (most recent call last):

  File "<ipython-input-6-98cb605ea9de>", line 1, in <module>
    import pyproj

  File "C:\ProgramData\Anaconda3\lib\site-packages\pyproj\__init__.py", line 62, in <module>
    from pyproj.crs import CRS

ModuleNotFoundError: No module named 'pyproj.crs'

At first, I thought it has problem with pyproj, but after I reinstalled the latest version of pyproj,

this error still occurred. I also tried to import cartopy.crs and same problem happened.

import cartopy.crs as ccrs
Traceback (most recent call last):

  File "<ipython-input-7-139fa5ad2567>", line 1, in <module>
    import cartopy.crs as ccrs

ModuleNotFoundError: No module named 'cartopy.crs'

How can I do with this problem? Is there a set of coordinate reference system that I can download

somewhere, or should I remove all about my python and reinstall? I'm really hoping to avoid that.

Any advice, please!

What finally helped me was

import pyximport
pyximport.install()

the _crs module is a pyx file (needs to be translated to C by Cython), pyximport allows it to be imported.
