Ah, that explains it. The Pyan package in PyPI requires Python 3 (tested on 3.4 and 3.6). It also only analyzes Python 3 code.

This is because support for Python 2 will in any case end on January 1, 2020. The compiler interface in the standard library is quite different between Python 2 and 3, so when I added Python 3 support to Pyan, Python 2 support unfortunately had to go.

For analyzing Python 2 code, you can use the final version of Pyan for Python 2, archived in @davidfraser's repo:

https://github.com/davidfraser/pyan/tree/pre-python3

It's just a single .py file, needs no installation. If you'd like to have a pyan command, like in the new version: copy pyan.py to somewhere along your PATH, rename that copy as just pyan (no .py), and then chmod +x pyan it to mark it as executable.
