AttributeError: module 'stem.util.log' has no attribute 'LogBuffer'

Latest git master of both Stem and Nyx gives me this error:

Thanks David! Stem 2.x breaks backward compatibility in several ways so Nyx is not expected to work with the git codebase. Once we have a Stem release I'll update Nyx to use the new codebase.

In the meantime please run Nyx with Stem 1.8.

Hi @atagar,

In the meantime, can you change nyx's requirements to include stem < 2 ? https://github.com/torproject/nyx/blob/master/setup.py#L82

[atagar]

Good point teor, can do. That said, it don't make a meaningful impact (that governs pip behavior, there there won't be a stem 2.0 release before nyx's codebase supports it).

[teor2345]

Is it possible to produce a more meaningful error message in nyx?

(That could be hard, because the error happens at import time.)

[atagar]

That's a great idea. When we add Stem 2.x compatibility I'll add a message when we have a version mismatch (since we'll lose 1.x support).
