Byobu attempts to load system Python3

[jenstroeger (Jens Troeger)]

I’ve installed byobu to play around with it, but receive the following error:

> byobu
/opt/local/bin/byobu-select-session: /opt/local/lib/byobu/include/select-session.py: /usr/bin/python3: bad interpreter: No such file or directory
/opt/local/bin/byobu-select-session: line 24: /opt/local/lib/byobu/include/select-session.py: Undefined error: 0

Looks like it tries to run the system’s Python3 interpreter (which ships only with 2.7) instead of MacPorts’ interpreter.

Addendum:

> sudo vim /opt/local/lib/byobu/include/select-session.py

and changing the first line to

#!/usr/bin/env python3

worked.

The ​libnewt port with python support compiled is required for the python part of byobu to function. But this port is built --without-python. So even if byobu properly loads Python from MacPorts, it would not have the required module.

byobu-5.130/usr/lib/byobu/include/constants

# Find a suitable python interpreter, if undefined
if [ -z "$BYOBU_PYTHON" ]; then
	if python3 -c "import snack" >/dev/null 2>&1; then
		export BYOBU_PYTHON="python3"
	elif python2 -c "import snack" >/dev/null 2>&1; then
		export BYOBU_PYTHON="python2"
	elif python -c "import snack" >/dev/null 2>&1; then
		export BYOBU_PYTHON="python"
	fi
fi

We need to package py-newt first.

Replying to l2dy:

We need to package py-newt first.

But calling libnewt's python modules py-newt would be wrong. That name should be reserved for the unrelated package at ​https://pypi.org/project/newt/

We need to package py-newt first.

This is now done; it's called py312-libnewt, etc.
