Em error BUFFERED_OPT

[RDaneelOlivav]

When I build the repo I get this error:

AttributeError: module 'em' has no attribute 'BUFFERED_OPT'

I uninstalled and reinstalled empy to be sure I had the latest version but it seems there is something wrong there. Any ideas?

Hi, I would need way more context. Which package build causes this? A quick search yields this, perhaps it will help: https://robotics.stackexchange.com/questions/109912/problem-with-building-nav2-on-ros-humble
