Answer 1

from the Locust docs:

On Windows, running pip install locustio might fail depedning on if you have a build environment set up correctly. In that case, the easiest way to get Locust running on windows is to first install the pre built binary package for pyzmq (and possibly for gevent and greenlet as well) .

You can find an unofficial collection of pre built python packages for windows here: http://www.lfd.uci.edu/~gohlke/pythonlibs/

When you've downloaded a pre-built .whl file, you can install it with:

 pip install pyzmq‑16.0.2‑cp36‑cp36m‑win32.whl 

Once you've done that you should be able to just: pip install locustio

Answer 2

Its possible that you have a version of python installed that is not supported by locustio. As of now, locustio is supported by Python 2.7, 3.4, 3.5, and 3.6. If you have a newer version of python (for example, python 3.7), the installation will fail.

Answer 3

I got similar problem but with exit code 1 when running pip install locustio .

I can confirm that fail on python 3.7.0, but it works ok on python 3.6.7 with no errors, so it's just a version compatibility issue
