在安装这个包时一直在报编译错误,后来下载到本地编译后发现报错的原因是python缺少了“yaml”这个库。pip install pyyaml 后成功安装!

@avisy: can you try:

$ pacman -Qo /opt/ros/melodic/lib/python3.8/site-packages/std_msgs /opt/ros/melodic/lib/python3.8/site-packages/std_msgs/ is owned by ros-melodic-std-msgs 0.5.12-1

roscore cannot start because:

    import std_msgs.msg
ModuleNotFoundError: No module named 'std_msgs'

update to ros-melodic-std-msgs 0.5.13 can solve it.
