I am having some trouble install lean locally and getting the following error:

ERROR: Failed building wheel for pandas
Failed to build dependency-injector pandas
ERROR: Could not build wheels for pandas, which is required to install pyproject.toml-based projects
I went back through the tutorial and read through some of the common errors but haven't found any documentation on this.
Any help would be greatly appreciated,

Update:
I have been able to get lean running locally and wanted to give an update in case anyone else runs into this this challenge in the future.
This may have been due to my Mac being based on Apple Silicon (M1) and went through installing Miniforge as the documentation outlined.
The solution that I found was installing the latest version of Anaconda with solved the challenge instead of using Miniforge.
