You can't mic view_config with add_view. Instead use view_config with a
scan:
from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.view import view_config
@view_config(renderer='json', route_name='create_account')
def hello_world(request):
return {'content':'Hello!'}
if __name__ == '__main__':
config = Configurator()
config.add_route('create_account', '/create')
config.scan()
app = config.make_wsgi_app()
server = make_server('0.0.0.0', 8080, app)
server.serve_forever()
