安装Shapely时，“ python setup.py egg_info”失败，错误代码为1

Question

When installing Shapely via PyCharm I got the following Error message:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\Anwender\AppData\Local\Temp\pip-install-h4bpp30v\Shapely\

and

C:\WINDOWS\system32>pip install Shapely

    Complete output from command python setup.py egg_info:

        self._handle = _dlopen(self._name, mode)
    OSError: [WinError 126] Das angegebene Modul wurde nicht gefunden

I already tried updating pip and setuptools but it still doesn't work.

Does anybody have something else I could try to get it running?

Shapely isn't available through pip. You need to download the Shapely Wheel here and run :
pip install Shapely-1.6.4.post1-cp37-cp37m-win_amd64.whl
(depending on the name of the package you decided to download. '37' means python 3.7 version. You can check your python version with python --version ).
