Deprecation error when installing requirements

[stalltron]

I get this error when installing the requirements in slack-archive-bot and I'm not sure if things are working correctly or not?

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
