python - Failed to start devlopment server -- BindError: Unable to find a consistent port localhost

Question

Google-app-engine development server runs great yesterday, but when I try to start it today. It only shout out this Error.

I tried use lsof -i:8080 / lsof -i:8000 to make sure these ports are not taken. I also tried use a --port arg to switch to another port. I even removed the gae folder and installed a new one. -- with no luck at all.

Maybe there is a obvious solution but I can't see it.

Here is the Oh-My-God trace stack..
