이것저것해서 정확히 뭐 때문에 문제가 해결된건지는 모르겠지만.. 한거를 적어보면.. 

echo 'export PATH=$PATH:/home/robo/.local/bin' >> ~/.bashrc

 

 

라이브러리 경로 설정 

export LD_LIBRARY_PATH=/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

 

 

LD_LIBRARY_PATH 확인 및 수정

echo $LD_LIBRARY_PATH

먼저 이거로 확인 .. 뭔가 많이 나왔음. 

 

$ echo $LD_LIBRARY_PATH
/lib/x86_64-linux-gnu:/home/robo/turtlebot3_ws/install/turtlebot3_msgs/lib:/home/robo/turtlebot3_ws/install/dynamixel_sdk_custom_interfaces/lib:/home/robo/turtlebot3_ws/install/dynamixel_sdk/lib:/usr/lib/x86_64-linux-gnu/gazebo-11/plugins:/opt/ros/humble/opt/rviz_ogre_vendor/lib:/opt/ros/humble/lib/x86_64-linux-gnu:/opt/ros/humble/lib:/usr/share/gazebo/../../lib/x86_64-linux-gnu/gazebo-11/plugins::/usr/share/gazebo/../../lib/x86_64-linux-gnu/gazebo-11/plugins:/usr/share/gazebo/../../lib/x86_64-linux-gnu/gazebo-11/plugins:

 

Qt 버전 경로가 중복되거나 불필요하게 설정되어 있는 경우 제거해야 합니다. 예를 들어, Qt 버전이 충돌하는 경로가 있는 경우 다음과 같이 환경 변수를 수정할 수 있습니다.

unset LD_LIBRARY_PATH

 

 export LD_LIBRARY_PATH=/lib/x86_64-linux-gnu:/opt/ros/humble/lib

 

PyQt5 제거 및 설치 (sudo 사용)

sudo pip uninstall PyQt5 PySide2

 

? 뭐지 마지막으로 한게 삭제한거네
