SyntaxError: invalid syntax

Pip installed unitypack-0.6.1.

Is it python3? bin/unityextract has interpreter shebang "env python", not python3. But also fails to work in python3 for a different reason.

[nyov]

Just installed everything with deps from git, for python3.
Now it works... a tiny bit.

Errors:
