Can't install via conda

[JoyMonteiro]

Describe the bug
I was trying to install TTK using the instructions given here: https://topology-tool-kit.github.io/installation.html

I was trying to install the VTK only version since I don't want Paraview dependency, so I tried
conda create -n ttk -c conda-forge "topologytoolkit * no_paraview*" as directed. mamba/conda can't seem to find topologytoolkit itself

error libmamba Could not solve for environment specs The following package could not be installed └─ topologytoolkit =* * does not exist (perhaps a typo or a missing channel). critical libmamba Could not solve for environment specs
I tried this on python 3.10 and 3.13 with no success.

Could you also let me know if the asterisks in the above command are correctly placed? I'm just hoping there is no typo which is causing this (I did try removing the asterisks, adding = etc., with no success)

To Reproduce
Steps to reproduce the behavior:

1. Follow the instructions given in the above mentioned page

Expected behavior
I expect topologytoolkit to install

System (please complete the following information):

• OS: Mac OS on M2 Apple Silicon

Could you please let me know if there is some issue with what I'm doing?

TIA,
Joy

I looked at the Azure pipeline in the feedstock repository. is it just that there is no Apple Silicon version yet?

[m-s-will]

Hi, yes that is indeed because there is no Apple Silicon version (on the conda-forge site you can see it only has win-64, osx-64 and linux-64 installers).
As a workaround at the moment you can create an x64 conda environment with Rosetta and install it in there.
