Replying to [comment:15 vbraun]:
> There are two different use cases:
> * A private build of Sage (everything user-writable) should not conflict
with another private numpy installation. You can use pip just fine without
the `--user` option. Then `PYTHONNOUSERSITE=yes` is the way to achieve
that.
> * A system-wide build of Sage (nothing user-writable, so just `pip
install foo` cannot work) should work with `pip --user`. This is the SMC
problem.
> Really this is a special case of distinguishing a build-from-source and
a binary install. Sage traditionally pretends that there is no difference,
but there is.
Agreed. I think the terminology "build-from-source" and "binary install"
is a little misleading though, since *I* did build the SMC install from
source myself. Maybe "system-wide" versus "personal install" would be a
better distinction.
Any thoughts about how to technically distinguish between these two types
of setups? A flag to ./configure on first build? Something else?
> BTW its now really easy to use pip for optional packages
Awesome -- a very good step in the right direction!
