模块未找到与我尝试导入的内容无关的模块错误

Question

I am trying to import a module in Python, but I keep getting the same error message, and I don't understand where it's coming from. I have even tried running the line below in a new bank document, and it still came up with he same issue.

import fastscape
from fastscape.models import basic_model

The error message it shows is the following:

Traceback (most recent call last):

  File ~\[redacted local file directory].py:2 in <module>
    import fastscape

  File ~\anaconda3\lib\site-packages\fastscape\__init__.py:6 in <module>
    from . import processes

  File ~\anaconda3\lib\site-packages\fastscape\processes\__init__.py:1 in <module>
    from .boundary import BorderBoundary

  File ~\anaconda3\lib\site-packages\fastscape\processes\boundary.py:6 in <module>
    from .context import FastscapelibContext

  File ~\anaconda3\lib\site-packages\fastscape\processes\context.py:1 in <module>
    import fastscapelib_fortran as fs

ModuleNotFoundError: No module named 'fastscapelib_fortran'

Except, as far as I am aware, there is no 'fastscapelib_fortran' in that model.

Following the documented install instructions works great.

$ conda create --name myproj
...
$ conda activate myproj
$
$ conda install fastscape -y -c conda-forge
...
$
$ python -c 'import fastscape'                                                                                               
$ python -c 'import fastscapelib_fortran'
$
$ conda list | grep fastscape                                                                                                
fastscape                 0.1.0beta3         pyhd8ed1ab_0    conda-forge                                                                                        
fastscapelib-f2py         2.8.3           py310h96b8b03_0    conda-forge
$ python --version
Python 3.10.8

The imports work fine, with no error. Conda pulled in all the deps.
