install error

[AII6]

Hello, when I install this package using pip install dex-retargeting it has an error:

Preparing metadata (setup.py) ... error

error: subprocess-exited-with-error

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

I tried other versions of pypandoc but it did not work. Before this error it searched many versions of package trimesh. How to solve it?

And the version of python is 3.9.19

This is because the version of the dependencies in the setup.py is not fixed, which causes pip to pull all possible versions of trimesh (and other libraries) to find the right combination, which eventually results in this error. It can be fixed by patching the setup.py with specific dependencies versions e.g. with Python 3.10 and pip 24.2 I did:

diff --git a/setup.py b/setup.py
index 8e5a66d..729f5c9 100644
