Could not find library geos_c or load any of its variants

Question

I use Python in Fedora 19. I wanted to run the following line:

import shapely.geometry

but the following error appears:

OSError: Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so']

I installed the package Shapely, and the following two libraries:

glibc-2.17-4.fc19.i686.rpm
geos-3.3.8-2.fc19.i686.rpm.

What can I do to solve the problem?

Installed shapely using pip, and had the same problem. So I went ahead and installed it like so:

sudo apt-get install libgeos-dev

And it worked. I'm running Ubuntu, so if you're on Fedora, you should run:

sudo yum install geos-devel

On MACOS you can run:

brew install geos

On Fedora, it should be `sudo yum install geos-devel` – kadee Mar 07 '17 at 16:10

on mac OS `brew install geos` – Otieno Rowland Jun 24 '20 at 07:48
If installing on ARM such as AWS Graviton2 instances (e.g. t4g instances) you might need `sudo yum install geos.aarch64 geos-devel.aarch64` – ChristopherTull Nov 08 '22 at 22:19
Thanks, my good friend!!! This saved my life and solved my issue with poetry install and lib shapely – Bruno Lemos May 14 '23 at 01:21

set the LD_LIBRARY_PATH, then run python

export LD_LIBRARY_PATH=/path_to/geos/lib:$LD_LIBRARY_PATH

python mytest.py

I am using Linux (Red Hat) and I got this error:

OSError: /home/[user]/.conda/envs/ox/lib/libgeos_c.so: cannot open shared object file: No such file or directory

What works for me:

conda install geos

Shapely loads geos via ctypes.

Try this in your python and see if you get anything:

from ctypes.util import find_library
find_library('geos_c')

If it doesn't work, then your geos installation is probably messed up. According to this, your geos should be in /usr/lib/libgeos_c.so.1. Is your library actually there?

No result means that python didn't find the library (it returned `None`). On linux, python uses `/sbin/ldconfig -p` to find libraries (you can run that command and look for libgeos). I would guess that your geos RPM is missing a dependency or didn't get installed properly. – Seth Nov 02 '13 at 22:47

I'm having the same problem. I ran `from ctypes.util import find_library find_library('geos_c')` And it returned `'libgeos_c.so.1'` so it looks like it's there... – bsf10 May 12 '14 at 16:12
For me, it returned something like: C:\Anaconda3\envs\my_env\Library\bin\geos_c.dll. As I could observe, the libgeos_c.so.1 was not presente within the bin directory, only this 'dll' file. – Philipe Riskalla Leal May 06 '21 at 22:27

In ubuntu, the following commands should take care of it. It all goes down to the following packages.

(Original 2017)

sudo apt-get install libgeos-c1 libgeos-3.4.2

EDIT: (updated versions 2020)

sudo apt-get install libgeos-c1v5 libgeos-3.7.1

If you're using Anaconda like I am and ran into this, copy the libgeos* files from /usr/lib to the anaconda/lib directory and try again... :) Hopefully this saves someone else, cause I have spent hours on this.

Do you remember any other step you needed to take? I first installed it via brew and then copied the files to the anaconda lib folder as you suggested, but I'm still getting `OSError: Could not find lib geos_c or load any of its variants ['/Library/Frameworks/GEOS.framework/Versions/Current/GEOS', '/opt/local/lib/libgeos_c.dylib'].` when I try to run my script. The strange part was that installing it via brew was enough for pip to start working. – Bani Nov 14 '15 at 22:17

I am using Anaconda on Ubuntu 16 and had similar error, even with libgeos-dev installed previously. The fix for me was `conda install geos` and after that, within my conda environment pip install shapely worked fine. – svohara Jun 28 '17 at 17:13

brew install geos

Just this installation solved my issues.

I had no problem on Jupyter Notebook but when I used PyCharm I encountered this issue. Tried multiple things windows on machine and the below troubleshooting steps fixed the issue

pip install geos

Go to PyCharm, File->Settings->Project->Project Interpreter(Check you have the right path where your python.exe file is there)->Add

Check that, on Virtualenv Environment -> Base Interpreter pointing to the right location where you have the python.exe

Same for System Interpreter->Interpreter And also Pipenv Environment -> Base Interpreter

Make sure all are pointing to the right path. I encountered this problem as I have multiple IDE and hence multiple directories where python.exe is available.They were pointing to incorrect directories.

During the troubleshooting I also uninstalled and re installed conda install shapelyas I am pointing to Anaconda directory from PyCharm. Hope it helps.

I had still issues after installing geos. What solved it for me (macOS 13.1) was

sudo kmdir /opt/local
sudo ln -s /opt/homebrew/lib /opt/local/lib

to let Shapely find libgeos_c.dylib in one of the locations it was willing to look for it.

I had the same problem, and to solve it, you need to add the lib path to ld.so.conf file.

To do this, Open the file:

sudo vi /etc/ld.so.conf

add this line

/usr/local/lib

And then

sudo /sbin/ldconfig

If you have macos, you should run:

brew install geos

Source distributions

If you want to build Shapely from source for compatibility with other modules that depend on GEOS (such as cartopy or osgeo.ogr) or want to use a different version of GEOS than the one included in the project wheels you should first install the GEOS library, Cython, and Numpy on your system (using apt, yum, brew, or other means) and then direct pip to ignore the binary wheels.

pip install shapely --no-binary shapely

If you've installed GEOS to a standard location, the geos-config program will be used to get compiler and linker options. If geos-config is not on your executable, it can be specified with a GEOS_CONFIG environment variable, e.g.:

GEOS_CONFIG=/path/to/geos-config pip install shapely

Could not find library geos_c or load any of its variants
