Seems like python 2.x is being used instead when it runs code_generator.py. I wonder if there are some stale build files causing this?

Did you try cleaning all build files or even try building using the latest master tarball from github in another directory to make sure you have an absolute latest, clean environment?

It's a clean build. Not sure it's related ninja. The plain old make works fine.
