Version

Plover version 4.0.0.dev0.144.gded92d7

Installed via: AUR repository plover-git

Notes

For me the Traceback makes sense since there really are no such modules but probably I'm missing something here...

Configuration

Arch Linux, i3 Window Manager, Python 3.6.1

We're getting it by this setuptools bug: pypa/setuptools#1054

As a workaround, pip install --user pyqt-distutils before installing from AUR.

Thank you @benoit-pierre! This solved the problem.

With #791 merged, using Plover's setup.py will now reliably fail if some setup requirements are missing, instead of building an incomplete version.
