安装 Shapely: OSError: [WinError 126] 找不到指定的模块

Question

I have to install Shapely package ( http://toblerity.org/shapely/project.html#installation ). But when I am using:

pip install Shapely

I am getting this error:

Collecting Shapely
  Using cached Shapely-1.5.17.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>

        self._handle = _dlopen(self._name, mode)
    OSError: [WinError 126] The specified module could not be found

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\AppData\Local\Temp\pip-build-mwuxcain\Shapely\

And, when I am using:

conda install shapely

I am getting this error:

Fetching package metadata ...........


PackageNotFoundError: Package not found: Conda could not find '

I am using Python 3.6.0 (Anaconda3) on Windows 10 (64-bit).

Please help. (nothing works)

Download WHL file using http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

Answer 2

You can also use

conda install -c conda-forge shapely

It worked for me.

Answer 3

Solution which worked for me (Windows Server):

1. Install osgeo4w from https://trac.osgeo.org/osgeo4w/

2. copy geos_c.dll and geos.dll to C:\\ProgramData\\Anaconda3\\Library\\bin

Answer 4

pip install shapely不起作用，但conda install shapely对我来说很好用（windows 用户）
