Error installing geopandas in python on mac m1

I'm trying to install geopandas on my M1 mac and I'm running into errors

I tried to pip install all the dependencies individually but where I'm tripping up is in the install of pyproj.

I installed PROJ using brew install proj and that worked fine

When I try to pip install pyproj, I get the follow error

Building wheels for collected packages: pyproj  

Building wheel for pyproj (pyproject.toml) ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Could not build wheels for pyproj, which is required to install pyproject.toml-based projects

Any help would be much appreciated

At the moment, installing geopandas on M1 macs can be achieved via conda or pip+homebrew.

GeoPandas itself is written in pure Python, so there is no issue running that on any architecture. However, it depends on other libraries that are written in other languages (C, C++) that need to be compiled specifically for M1 chips. While you could compile it yourself, I am not going to cover this option as it is not user friendly.

There are three possible sources of required libraries - pip wheels, conda-forge, and Homebrew.

When a Python package requires C dependency, it can create wheels with the dependency compiled for each system and chip architecture. See for example pygeos - https://pypi.org/project/pygeos/#files. What you need is *macosx_11_0_arm64.whl . If your package doesn't offer it, you have to find another way of installing than pip. Since GeoPandas requires shapely and fiona (among others) that do not have these wheels, you should look elsewhere - either on conda-forge or Homebrew. Below are both options tested as of today.

Conda and conda-forge way (recommended)

Conda-forge currently has all packages geopandas needs

Install M1 version of miniforge or mambaforge. It can be downloaded from here - https://github.com/conda-forge/miniforge.

conda install -c conda-forge geopandas pygeos

Note: if you install x86 (Intel) version of conda, it will run under Rosetta2 and install all packages using x86 architecture, meaning that everything will run under emulation. Try to avoid that.

Pip and Homebrew way

Homebrew can install C libraries compiled for M1. Python packages will find and use them.

Using an environment with Python 3.9

Install shapely:

brew install geos
export DYLD_LIBRARY_PATH=/opt/homebrew/opt/geos/lib/
pip install shapely

DYLD_LIBRARY_PATH is needed for shapely to find GEOS installation.

Install fiona:

brew install gdal
pip install fiona

Install pyproj:

brew install proj
pip install pyproj

Install geopandas and pygeos for speedups:

pip install pygeos
pip install geopandas

I was stuck with the same problem, I also tried setting the environment values for PROJ_DIR, PROJ_LIBDIR, PROJ_INCDIR but perhaps setting the values is causing the error, so closed the terminal and tried again and was able to install correctly
