Local install of Pyrobosim throws error "AttributeError processing template 'msg.idl.em'" during local install #283

Closed EdwardCalvert closed 1 month ago

Hi, I am trying to run pyrobosim with the local install method. I've followed the documentation, and seem to get the same error message every time after installation, which I have included below. I was just wondering how to fix this error?

Cheers
