OSError:无法找到或加载spatialindex_c.dll

我已经安装了菲奥娜,Shauley,GDAL,RTER和PYPRJ的WHL文件。Geopandas也通过pip安装。但我在导入时遇到以下错误:

import geopandas
Traceback (most recent call last):

  File "<ipython-input-14-c9ee6bd24dbc>", line 1, in <module>
    import geopandas

    raise OSError("could not find or load spatialindex_c.dll")

OSError: could not find or load spatialindex_c.dll

还有以下错误:

import fiona
Traceback (most recent call last):

  File "<ipython-input-16-cc872b235141>", line 1, in <module>
    import fiona

  File "C:\ProgramData\Anaconda3\lib\site-packages\fiona\__init__.py", line 77, in <module>
    from fiona.collection import Collection, BytesCollection, vsi_path

  File "C:\ProgramData\Anaconda3\lib\site-packages\fiona\collection.py", line 9, in <module>
    from fiona.ogrext import Iterator, ItemsIterator, KeysIterator

  File "fiona\ogrext.pyx", line 25, in init fiona.ogrext

ImportError: cannot import name compat

谁能帮帮我吗? 我不知道如何解决这个问题。谢谢和问候。
