Multiple Python versions are installed in the same image #253
Description
In the Docker images, multiple Python versions can be found. For example:
Python 2.7, 3.5 and 3.6 in the python:3.6.4-stretch image:
$ docker run python:3.6.4-stretch bash -c 'ls -d /usr/bin/python?.? /usr/local/bin/python?.? /usr/local/lib/python?.?'
/usr/bin/python2.7
/usr/bin/python3.5
/usr/local/bin/python3.6
/usr/local/lib/python2.7
/usr/local/lib/python3.5
/usr/local/lib/python3.6
Python 2.7 and 3.6 in the python:3.6.3 image:
$ docker run python:3.6.4 bash -c 'ls -d /usr/bin/python?.? /usr/local/bin/python?.? /usr/local/lib/python*'
/usr/bin/python2.7
/usr/local/bin/python3.6
/usr/local/lib/python2.7
/usr/local/lib/python3.6
Can this be fixed somehow?
Fortunately, the -slim packages seem to have one proper Python version installed.

This is kind of an unfortunate side-effect of our use of
buildpack-depsin the non-slim variants -- some of the packages that it includes require Python, and there's not a lot we can do to fix that (it's the nature of including the whole kitchen sink).We have made sure that
PATHis set appropriately such that the Python installed by this image is preferred.
