Never loads?

Installed on OSX and I’m getting the following issue:

Adrianos-MacBook-Pro:locust adriano$ locust --host=http://domain.com
/usr/local/lib/python2.7/site-packages/locust/rpc/__init__.py:6: UserWarning: WARNING: Using pure Python socket RPC implementation instead of zmq. If running in distributed mode, this could cause a performance decrease. We recommend you to install the pyzmq python package when running in distributed mode.

warnings.warn("WARNING: Using pure Python socket RPC implementation instead of zmq. If running in distributed mode, this could cause a performance decrease. We recommend you to install the pyzmq python package when running in distributed mode.")

[2015-07-03 02:05:26,170] Adrianos-MacBook-Pro.local/INFO/locust.main: Starting Locust 0.7.3

I’m not using distributed mode.

Also happens when I tried installing in a custom vagrant box (Ubuntu 14.04) I already had on my system. I followed the instructions perfectly from the docs page.

that’s just a warning… there is no error

In alpine’s case, you might also need g++ installed

e.g. on alpine you need apk add --update g++ (even pyzmq is installed successfully after you installed g++, you still need to keep g++ installed)

if you uninstall g++ after successfully installing pip install pyzmq, that warning also comes up
