GAE - BindError: Unable to bind localhost:8080

Question

I'm testing Facebook's sample Google App Engine app by following the steps under "Getting Started".

When I try to run the app on localhost from within the Windows launcher, it waits for about 5 seconds and then displays a yellow exclamation point. The logs give the error:

google.appengine.tools.devappserver2.wsgi_server.BindError: Unable to bind localhost:8080

What is causing this error?

Answer 1

This command will help you to delete the process using the port :8002 without exception.

lsof -P | grep ':8002' | awk '{print $2}' | xargs kill -9
