executing ship_it with python3 seems to make a python2 virtualenv

[robdennis]

which ship_it shows the ship_it from the redhat-provided python 3 executable:
/opt/rh/rh-python35/root/usr/bin/ship_it

[robdennis]

@jawnb have you gotten this to actually build a python3 rpm?

[alvin-huang]

When I pip install ship_it in py35 and set up PATH:

bash-4.2# echo $PATH
/opt/rh/rh-python35/root/usr/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
bash-4.2# which ship_it
/opt/rh/rh-python35/root/usr/bin/ship_it

It looks like when I run ship_it manifest.yaml it uses py2.7 while when I fully qualify the ship_it binary /opt/rh/rh-python35/root/usr/bin/ship_it manifest.yaml it uses py3.5

[robdennis]

@alvin-huang THAT IS REALLY ANNOYING. There's probably a slightly more resilient equivalent to sys.executable that we could use instead.
