Are you sure about that? A fresh ubuntu 20.04 install for me defaulted to python2 for 'python' and 'pip'. From what I've read, that should always be the case. Anything expressly needing python3 should be explicit. But then ubuntu has python-is-python2 and python-is-python3 packages to set the default, so I'm confused... (I was trying to figure out what to do with spdxcheck.py which broke on 20.04 because the new version of the 'git' python module is python3 only and spdxcheck.py was using python2.) In any case, pip3 always works and pip may or may not work. So I think the answer here is obvious. > Pass --user explicitly in the example so it is clear that this > gets installed in the user home directory. > > Add an additional instruction on how to upgrade the project, > not everyone is aware of how pip works. BTW, releases are now on PyPi, so you can do just 'pip3 install dtschema'.
