匀称的 OSError：找不到 lib c 或加载其任何变体 []

Question

我只是想使用演示代码。我在 Jupyter Notebook 中运行以下命令：

from shapely.geometry import shape

这给了我以下内容：

OSError                                   Traceback (most recent call last)

     81         _lgeos = load_dll('geos_c', fallbacks=alt_paths)
     82 
---> 83     free = load_dll('c').free
     84     free.argtypes = [c_void_p]
     85     free.restype = None

/Users/hkwik/anaconda/lib/python2.7/site-packages/shapely/geos.py in load_dll(libname, fallbacks, mode)
     59         raise OSError(
     60             "Could not find lib {0} or load any of its variants {1}.".format(
---> 61                 libname, fallbacks or []))
     62 
     63 _lgeos = None

OSError: Could not find lib c or load any of its variants [].

但是，如果我从解释器运行，一切都很好。

知道发生了什么吗？

Answer 1

我只是卸载了 Shapely 并重新安装它来解决这个问题。

python -m pip uninstall shapely

python -m pip install shapely

Answer 2

您可以尝试重置环境变量DYLD_FALLBACK_LIBRARY_PATH：

export DYLD_FALLBACK_LIBRARY_PATH=$(HOME)/lib:/usr/local/lib:/lib:/usr/lib

Answer 3

试试这个可能对你有帮助：

pip install --upgrade --force-reinstall shapely
