Run Salt minion specifying the Python path

Question

Is there any way to specify the python interpreter that has to be used to run the salt-minion?

I have several salt minions running on a local network. Most of them are working correctly but some minions are throwing errors and our guess is that the minion is running with python 3 instead of python 2 (we need to use salt-2018.3.4-py2)

If I run python --version it says the version is 3.7. How can we force the minion to use python 2.7?

Thanks.

I would say that it directly depends on your installation package. If you installed salt-2018.3.4-py2 it means it will run with py2.

On my minion, salt-2019.2-py3 is installed and I have

$ python -V
Python 2.7.13
$ salt-minion --versions
