我尝试在 Python 中按如下方式导入底图：

from mpl_toolkits.basemap import Basemap

我收到以下错误：

Traceback (most recent call last):

  File "<ipython-input-16-880204a64918>", line 2, in <module>
    from mpl_toolkits.basemap import Basemap

  File "C:\Users\bakhadher\AppData\Local\Continuum\anaconda3\lib\site-packages\mpl_toolkits\basemap\__init__.py", line 155, in <module>
    pyproj_datadir = os.environ['PROJ_LIB']

  File "C:\Users\bakhadher\AppData\Local\Continuum\anaconda3\lib\os.py", line 678, in __getitem__
    raise KeyError(key) from None

KeyError: 'PROJ_LIB'
