[macOS 10.15.4] Gazebo 11 Run Error - dyld: Symbol not found (libgazebo_gui.11.dylib)

edit

Hi!

I installed Gazebo on my Mac with the one-liner method, but when I try to run it, it shows:

dyld: Symbol not found: __ZN6gazebo3gui10DataLogger16staticMetaObjectE
Referenced from: /usr/local/lib/libgazebo_gui.11.dylib
Expected in: flat namespace
in /usr/local/lib/libgazebo_gui.11.dylib
zsh: abort gazebo

Another person also posted the same problem at the end of this Gazebo answers question.

What is this problem and how would I fix it?

Cheers,
L
