command 'install' has no such option 'single_version_externally_managed'

[probonopd]

Getting this when trying to run on Travis CI. Seemingly not getting this on a local Xubuntu 18.04.
Could it be that something from the host's Python is still being used?

[conda/stderr] distutils.errors.DistutilsOptionError: error in setup.cfg: command 'install' has no such option 'single_version_externally_managed'
ERROR: Failed to run plugin: conda (exit code: 2)

This runs locally but fails on Travis CI:

Deleted single_version_externally_managed from the application's setup.cfg. Now it builds on Travis CI.

Was about to reply that this seems like an issue in the original setup script. Great that it works now.

That /home/travis/build/probonopd/ must be eradicated from the build products...

We have something that begins to launch now, but:

This application failed to start because it could not find or load the Qt platform plugin "xcb"

Reinstalling the application may fix this problem.

Not sure what is going on here... ping @TheAssassin any idea?
