Unfortunately, dev_appserver does not yet work with Python 3.x(See https://cloud.google.com/appengine/docs/standard/python3/testing-and-deploying-your-app#local-dev-server). You need to run it from a virtualenv which is running python 2.7.
Alternatively, as specified in https://cloud.google.com/appengine/docs/standard/python3/testing-and-deploying-your-app, you can choose to not use dev_appserver at all.
