Python, GEOS and Shapely on Windows 64

Question

When trying to install Shapely on my Windows 64bit computer, I cannot get the GEOS library to work.

So far, I have run the OSGeo4W installer from which I installed GDAL (I believe the geos library is included in that package). After that, I checked and I have geos_c.dll on my C:\OSGeo4W\bin directory, but either I have missed some configuration steps or the library does not work.

I need Shapely to work, so I also ran pip install shapely after installing GDAL, and it apparently worked (although it could not find the C library for GEOS).

In my code, I can import Shapely, but when I try to use it, I get an error telling me "geos.dll" is not found.

Any help with this will be very appreciated. Thanks!

Maybe you could use an installer at the bottom of [this](http://pypi.python.org/pypi/Shapely/1.2b6) page. That should include geos. — RickyA, Nov 22 '12 at 11:16
In my case, I had to switch to a lower (3.10 to 3.9) Python version — Maksim Kuzmin, Dec 16 '21 at 18:40

Anaconda/Miniconda users should install Shapely (and dependencies) with:

conda install shapely

As 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.

Make sure you install the version that matches your Python installation, NOT your OS. I made the mistake of installing the 64 bit shapely since I'm running 64 bit Windows, but my Python is 32 bit, and it gave me a similar "geos_c.dll" is not found. – Tanner Semerad Sep 24 '13 at 00:17

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.

This version is from 2010-04-13, and was compiled for 32-bit Python 2.4, 2.5 and 2.6. – Mike T Apr 16 '14 at 11:00

you can find newer versions by modifying the version number in the url. E.g. [version 1.3.0](https://pypi.python.org/pypi/Shapely/1.3.0) is from 2014 and works with python 2.7 and 3.3 – joelostblom Mar 23 '15 at 14:25

I tried the method of @jozef but failed even I imported the folder to the path.

A straightforward solution: add geos_c.dll, geos.dll to the library folder of your python environment. Then it works.

I've made it installing wheels for GDAL (and Fiona, in my case; might not be required) from https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal Providing a path to the geos_c.dll didn't work. Neither putting them into venv/Lib.
