Old version of Panadas not getting installed

[Sourdoc]

Hi,
I am trying to install export2graphlan using pip. I am using virtual machine which already has latest version of pandas (2.2.2) installed. When I am trying to create a python virtual environment and install pandas 0.13.1, it is not detecting the already install version and not allowing me to install 0.13.1 anyway. So I was wondering if you are planning to release a newer version of export2graphlan that supports latest version of pandas. I have installed metaphlan 4.1 which doesn't have export2graphlan so I was also wondering if you are planning to include export2graphlan.py in latest versions of metaphlan.

`pip install export2graphlan

Can't uninstall 'pandas'. No files were found to uninstall.
DEPRECATION: pandas is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559
