[matplotlib-devel] Odd install error

[Benjamin R. <ben...@ou...>]

So, I was working from a completely fresh virtualenv, installing a package
that had a matplotlib dependency. As it happens to be, the dependencies in
this package lists matplotlib prior to numpy, so matplotlib got processed
first. For whatever reason, while processing matplotlib, it didn't seem to
think that it depended upon NumPy, but failed anyway when it couldn't find
it.  See the following output:

Best match: matplotlib 1.3.0

Unfortunately, this is a known bug in setuptools.  It has no concept of 
"build time" dependencies, so it probably computed all of the 
dependencies correctly, but it doesn't install them in the correct order 
-- it just assumes that as long as everything gets installed it will 
work when it's finally run.  This is the same problem that means even 
though matplotlib specifies numpy as a dependency, "pip install 
matplotlib" will not work unless numpy is already installed.  This is a 
perennial problem, and apparently the setuptools guys spend very little 
time considering C extensions at all.

There is setup_requires, and from the documentation that I see, I wonder if
listing NumPy in both build_requires and install_requires invokes a special
handling to install setup requirements in the same place as install
requirements?

Wow -- setup_requires is new to me.  It's worth a shot.
