Okay, I did the following to avoid this:
import sys, os.path
modulepath = os.path.abspath(os.path.dirname(sys.argv[0]))
def import_local_module(name):
"""Load a module from the local modules directory.
Loading e.g. a local "parser" module is difficult because on
Windows, the stdlib parser module is a built-in and thus loaded
with higher priority. With
http://www.python.org/dev/peps/pep-0328/ it may become simpler.
:Parameters:
- `name`: name of the module, as it would be given to
``import``.
:Return:
the module object or ``None`` if none was found
:rtype:
module
"""
import imp
try:
return sys.modules[name]
except KeyError:
pass
fp, pathname, description = imp.find_module(name, [modulepath])
try:
return imp.load_module(name, fp, pathname, description)
finally:
# Since we may exit via an exception, close fp explicitly.
if fp:
fp.close()
Tschö,
Torsten.
