How to change the default (binary) python version in a FreeBSD jail?

garage_greg

In a jail, I have installed python3.6 along python3.4 . Both were installed using pkg install , no ports. I want to keep the 3.4 version for some time, but set the 3.6 as default. Answers found in internet, like this one or this one either involve to myself link /usr/local/bin/python to python3.6 (what must be done again after any upgrade of the default python, what I'd like to avoid; plus there's no such link anyway); or to set DEFAULT_VERSIONS...

Great question — answering as the UphillTech team:

All binaries were prebuilt with default settings and current default Python is 3.6. To achieve your goal you can install desired Python version as a binary then you can set it in DEFAULT_VERSIONS in /etc/make.conf and then install uwsgi from ports using this version. I do this procedure in automated way with Python3.7 which is't default ATM. Alternatively, you can test if your application works fine under Python 3.6 (upgrade to your code should be minimal if any) and continue with default binaries.
