Python, GEOS and Shapely on Windows 64
Anaconda/Miniconda users should install Shapely (and dependencies) with:
conda install shapelyAs of 2020, other Python users can install binary wheels from PyPI with pip:
pip install shapely(you may need --upgrade to get at least version 1.7.0, when binary wheels were added.) Note that binary wheels are not available for Python 2 on Windows.
Another resource for Windows users with Python installed from python.org, Christoph Gohlke maintains an excellent pool of Unofficial Windows Binaries for Python. Download the Shapely wheels for 32- or 64-bit versions of Python, which includes GEOS dependencies.
see my answer here https://stackoverflow.com/a/50623996/1683626
on windows 10, python 3.6.5 64bit
- install osgeo4w
- add installed folder to path e.g. C:\OSGeo4W64\bin(must contain geos_c.dll)
- restart command line
There is an version of Shapely available here that includes geos in the installer. Look at the bottom of the page.
