We are doing the best we can so you do not have to read this section.

That said, we have included solutions (or at least explanations) for some common problems below.

If you do not find a solution to your problem here, please ask for help!

ConnectionError: localhost:6379. nodename nor servname provided, or not known

Make sure /etc/hosts has correct mapping to localhost.

IOError: [Errno 24] Too many open files

Make sure that max number of connections to redis-server and the max number of file handlers in operating system have access to required memory.

To fix this, increase the open file limit for non-root user:

$ ulimit -n 1024

ERROR: InterpreterNotFound: pypy

You need to install Pypy so that it can be found by tox.
