Install Shapely: OSError: [WinError 126] The specified module could not be found

我必须安装 Shapely 包 (http://toblerity.org/shapely/project.html#installation)。 但是当我使用时:

pip install Shapely

我收到这个错误:

Collecting Shapely
  Using cached Shapely-1.5.17.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

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

而且,当我使用时:

conda install shapely

我收到这个错误:

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


PackageNotFoundError: Package not found: Conda could not find '

我在 Windows 10(64 位)上使用 Python 3.6.0 (Anaconda3)。

请帮忙。 (没有任何作用)

使用 http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

下载 WHL 文件

安装:

python -m pip install Shapely-1.5.17-cp36-cp36m-win_amd64.whl

Ubuntu:

pip install shapely==1.6b2

您也可以使用

conda install -c conda-forge shapely

对我有用。

对我有用的解决方案(Windows 服务器):

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

    安装 osgeo4w
  2. 复制geos_c.dll和geos.dll到C:\ProgramData\Anaconda3\Library\bin

pip install shapely 没有工作但是 conda install shapely 对我来说很好(windows 用户)

copy "[env path]\LIb\site-packages\shapely\DLLs\geos*.dll" to "[env path]\Library\bin"
