Question

I’m implementing an app using django 1.3.1 and python 2.7.

This app uses Facebook login, but I’m getting this message error in return:

TypeError at /promo-racao/
cannot make memory view because object does not have the buffer interface

Weird thing is that locally it works. This error occurs only on the webserver, but the environment is the same. And it doesn’t point to a specific file or code line.

Searching Google for this error does not return anything useful. Here is the traceback I got from Django:

This is a bug in gevent. It was fixed in 0.13.7. Just upgrade gevent, and you should be fine. See: http://www.gevent.org/changelog.html
