Hmmmm, my email post doesn't seem to be showing up, so I'm going to
try it through the web, this will probably end up being a re-post :)
Hi Brad,
This is a conflict with package names. Our packages are
google.appengine, and you are trying to use a packaged named
google.protobuf.
You should include the google.protobuf files in your application's
source directory, but you need to do a bit of sys.modules magic to get
it to work.
First, make a file called import_fixer.py. The contents should be:
import os
import sys
BASE_PACKAGE = 'google'
def FixImports(*packages):
topdir = os.path.dirname(__file__)
def ImportPackage(full_package):
"""Import a fully qualified package."""
imported_module = __import__(full_package, globals(), locals())
# Check if the override path already exists for the module; if it
does,
# that means we've already fixed imports.
original_module = sys.modules[full_package]
lib_path = os.path.join(topdir, full_package.replace('.', '/'))
if lib_path not in original_module.__path__:
# Insert after runtime path, but before anything else
original_module.__path__.insert(1, lib_path)
ImportPackage(BASE_PACKAGE)
for package in packages:
# For each package, we need to import all of its parent packages.
dirs = package.split('.')
full_package = BASE_PACKAGE
for my_dir in dirs:
full_package = '%s.%s' % (full_package, my_dir)
ImportPackage(full_package)
~~~
Then, in your application file, do the following after importing all
your appengine modules:
import import_fixer
import_fixer.FixImports('protobuf')
from google.protobuf import descriptor
Then your imports should work.
