Thank you for filing this issue.

At first glance this looks like you installed aider in an environment with many other Python modules and aider's dependencies got mixed up. Can you please try to install aider in a separate Python environment? Either with anaconda (which you seem to be using) or venv or even pipx?

This document may be helpful -> https://aider.chat/docs/troubleshooting/imports.html

Thanks for trying aider and filing this issue.

This looks like a duplicate of #1437. Please see the comments there for more information, and feel free to continue the discussion within that issue.

I'm going to close this issue for now. But please let me know if you think this is actually a distinct issue and I will reopen this issue.
