I got pybtex from pip, for what it is worth.

[Andrey Golovizin]

Pybtex uses Python 2 syntax and 2to3. The sources are automatically converted to Python 3 when setup.py install is run with python3. This should work with pip, too.

Did you run pip with python3? What was the exact command?

[Andrey Golovizin]

OK, please reopen if still relevant.
