As stated in the README we don't support conda.

Hi @alemuntoni thank you for your reminder, I deactivated conda and still got this error:

I installed pymeshlab through pip3 install pymeshlab, and the default pymeshlab version is 2022.2.post3. I downloaded the latest pymeshlab-2023.12.post1-cp38-cp38-manylinux_2_31_x86_64.whl from https://pypi.org but cannot install: ERROR: pymeshlab-2023.12.post1-cp38-cp38-manylinux_2_31_x86_64.whl is not a supported wheel on this platform.
