Hello everybody,
I am trying to build sage with python3 (I asked for help here before, but
got only little).
It fails, of course (see log below for "make build"). I would like to
understand how.
I am in a python3 virtualenv, and SAGE_ROOT/local/bin/python launches a
python3
This python3 complains that it cannot find pkg_resources, as follows (from
the shell)
./local/bin/python -c 'import pkg_resources;
pkg_resources.get_distribution("matplotlib").version'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named 'pkg_resources'
but instead it seems to pick the py2 pkg_resources, when called inside the
sage-env script.
Any idea ? By the way, please review https://trac.sagemath.org/ticket/20909
and https://trac.sagemath.org/ticket/20910, which are needed to reach this
point.
Frederic
