This test will fail because a previous attempt to fix a merge error
in site.py was incorrect, but the test wasn't running so it wasn't
caught. The next commit will fix the site.py bug.
It now always checks, instead of only when the LICENSE file doesn't exist. It
is also protected by the 'network' resource, and uses a HEAD request since we
are only doing an existence check.
ImportError.
The exception is raised by import when a module could not be found.
Technically this is defined as no viable loader could be found for the
specified module. This includes ``from ... import`` statements so that
the module usage is consistent for all situations where import
couldn't find what was requested.
This should allow for the common idiom of::
try:
import something
except ImportError:
pass
to be updated to using ModuleNotFoundError and not accidentally mask
ImportError messages that should propagate (e.g. issues with a
loader).
This work was driven by the fact that the ``from ... import``
statement needed to be able to tell the difference between an
ImportError that simply couldn't find a module (and thus silence the
exception so that ceval can raise it) and an ImportError that
represented an actual problem.
If a .pth file contained an error, it could cause a traceback in site.py,
terminating its processing. In 2.7 and 3.2, the interpreter will then not
start. Previously, a message would print saying to use -v to get the
traceback. In either case, the traceback generated for a failed .pth file did
not include the .pth filename, making it difficult to debug the problem. Now
site.py reports not only the .pth filename but also the line number causing the
error, and just skips the remainder of the file.

test_site was failing under darwin for non-framework builds because a test was
assuming framework-specific site-packages directories were being used.
