How can I control which interpreter hatch uses?

[jamiekt]

On my local machine the default interpreter is python3.11 however I want to debug a problem in python3.10. I use pyenv to install different python versions and control which one I'm using so I switch to python3.10 however my hatch environment still continues to use python3.11

➜  pyenv shell 3.10
➜  hatch env prune
➜  python --version
Python 3.10.10
➜  hatch run python --version
Python 3.11.2
➜  ls -l "$(hatch run which python)"

As can be seen the interpreter that hatch is using is python 3.11.

How does hatch determine which interpreter to use and is there any way to force it to use an interpreter of my choice?

Answering my own question... use HATCH_PYTHON to specify the python interpreter for the hatch environment

➜  export HATCH_PYTHON=~/.pyenv/versions/3.10.10/bin/python    
➜  hatch run python --version
Python 3.10.10

I found this information at https://hatch.pypa.io/latest/plugins/environment/virtual/#options

FYI in the documentation I'm going to begin discouraging the use of pyenv now that we have these features:

• Implement Python management #970
• Automatically download Python distributions for virtual environments #1002
