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

same error here. any solution?
strangely, I managed to install it without problems in a conda environment with python 3.9 a month ago. Now I just cannot in anyway

[tomvanmele]

i will have a look.
but fyi, we made a few changes to be able to make the package available on conda-forge.
if you don't actually need a dev install, would you mind giving that a try?
it should be available from there for windows, osx, and linux for python 3.8, 3.9, 3.10...

conda install compas_libigl

[tomvanmele]

i think the problem with the dev install might be that we now use pybind from conda instead of through the git submodules as before. if that is the case, the solution should be as simple as updating the dev install command to

conda create -n igl-dev python=3.9 git cmake">=3.14" boost eigen=3.3 pybind11

and the rest the same as before...

[tomvanmele]

note that eigen=3.3 is only needed to make sure the binding can be installed in the same env as compas_cgal. there i have issues getting the code to work with newer versions of Eigen. for whatever reason i throws an error whenever i try to assign values to the Eigen dense matrix. for example in compas.cpp on line 168

V(vd, 0) = (double)location[vd][0];

if someone can help me figure out why that is the case, we can remove that restriction...

[tomvanmele]

new instructions are here: https://compas.dev/compas_libigl
let me know if that doesn't work...

hi @tomvanmele , sorry for the late response, conda install worked without problems for me. Thank you very much for this amazing tool
