datapusher install: no application found

I am trying to run Datapusher on ckan 2.9.

I follow the installation pages describe in https://github.com/ckan/datapusher/blob/master/README.md

And also seems to work, but when I run it and I try in the front-end to "Upload to DataStore" I get the following error:

--- no python application found, check your startup logs for errors ---
[uwsgi-http key: 127.0.0.1:8800 client_addr: 127.0.0.1 client_port: 64132] hr_instance_read(): Connection reset by peer [plugins/http/http.c line 647]

And on the Browser: Upload error: An Error occurred while sending the job: 500 Server Error: Internal Server Error for url: http://127.0.0.1:8800/job

I would appreciate if you could help me on this one. Thanks!
