Built distributions don’t require compiling Shapely and its dependencies,
and can be installed using
conda. In addition, Shapely is also
available via some system package management tools like apt.
Installation from PyPI#
Shapely is available as a binary distribution (wheel) for Linux, macOS, and Windows platforms on PyPI. The distribution includes the most recent version of GEOS available at the time of the Shapely release. Install the binary wheel with pip as follows:
$ pip install shapely
Installation using conda#
Shapely is available on the conda-forge channel. Install as follows:
$ conda install shapely --channel conda-forge
Installation from source with custom GEOS libary#
You may want to use a specific GEOS version or a GEOS distribution that is already present on your system (for compatibility with other modules that depend on GEOS, such as cartopy or osgeo.ogr). In such cases you will need to ensure the GEOS library is installed on your system and then compile Shapely from source yourself, by directing pip to ignore the binary wheels.
$ sudo apt install libgeos-dev # skip this if you already have GEOS $ pip install shapely --no-binary shapely
$ brew install geos # skip this if you already have GEOS $ pip install shapely --no-binary shapely
If you’ve installed GEOS to a standard location on Linux or macOS, the installation will automatically
find it using
geos-config. See the notes below on GEOS discovery at compile time
to configure this.
We do not have a recipe for Windows platforms. The following steps should enable you to build Shapely yourself:
Get a C compiler applicable to your Python version (https://wiki.python.org/moin/WindowsCompilers)
Download and install a GEOS binary (https://trac.osgeo.org/osgeo4w/)
Set GEOS_INCLUDE_PATH and GEOS_LIBRARY_PATH environment variables (see below for notes on GEOS discovery)
pip install shapely --no-binary
Make sure the GEOS .dll files are available on the PATH
Installation for local development#
This is similar to installing with a custom GEOS binary, but then instead of installing Shapely with pip from PyPI, you clone the package from Github:
$ git clone email@example.com:shapely/shapely.git $ cd shapely/
Install it in development mode using
$ pip install -e .[test]
For development, use of a virtual environment is strongly recommended. For example
$ python3 -m venv . $ source bin/activate (env) $ pip install -e .[test]
$ conda create -n env python=3 geos numpy cython pytest $ conda activate env (env) $ pip install -e .
Shapely can be tested using
$ pip install pytest # or shapely[test] $ pytest --pyargs shapely.tests
GEOS discovery (compile time)#
If GEOS is installed on Linux or macOS, the
geos-config command line utility
should be available and
pip will find GEOS automatically.
If the correct
geos-config is not on the PATH, you can add it as follows (on Linux/macOS):
$ export PATH=/path/to/geos/bin:$PATH
Alternatively, you can specify where Shapely should look for GEOS library and header files using environment variables (on Linux/macOS):
$ export GEOS_INCLUDE_PATH=/path/to/geos/include $ export GEOS_LIBRARY_PATH=/path/to/geos/lib
On Windows, there is no
geos-config and the include and lib folders need to be
specified manually in any case:
$ set GEOS_INCLUDE_PATH=C:\path\to\geos\include $ set GEOS_LIBRARY_PATH=C:\path\to\geos\lib
Common locations of GEOS (to be suffixed by
GEOS discovery (runtime)#
Shapely is dynamically linked to GEOS. This means that the same GEOS library that was used during Shapely compilation is required on your system at runtime. When using Shapely that was distributed as a binary wheel or through conda, this is automatically the case and you can stop reading.
In other cases this can be tricky, especially if you have multiple GEOS installations next to each other. We only include some guidelines here to address this issue as this document is not intended as a general guide of shared library discovery.
If you encounter exceptions like:
ImportError: libgeos_c.so.1: cannot open shared object file: No such file or directory
You will have to make the shared library file available to the Python interpreter. There are in general four ways of making Python aware of the location of shared library:
Copy the shared libraries into the
shapelymodule directory (this is how Windows binary wheels work: they are distributed with the correct dlls in the
Copy the shared libraries into the library directory of the Python interpreter (this is how Anaconda environments work)
Copy the shared libraries into some system location (
/usr/local/lib, this happens if you installed GEOS through
Add the shared library location to a the dynamic linker path variable at runtime. (Advanced usage; Linux and macOS only; on Windows this method was deprecated in Python 3.8)
The filenames of the GEOS shared libraries are:
Note that Shapely does not make use of any RUNPATH (RPATH) header. The location of the GEOS shared library is not stored inside the compiled Shapely library.
