卸载cmake重装后发现ros功能不完整（如roslaunch、rosrun等命令无法使用）

注意：绝对不要卸载cmake重装，因为卸载cmake时会将其他插件卸载掉。。。

1、重新安装ros

安装教程：https://blog.csdn/m0_51759289/article/details/123865295

在安装ros-melodic-desktop-full报错：

下列软件包有未满足的依赖关系：
ros-melodic-desktop-full : 依赖: ros-melodic-simulators 但是它将不会被安装
依赖: ros-melodic-urdf-sim-tutorial 但是它将不会被安装

解决方法：
使用aptitude安装
1）安装aptitude工具

apt-get install aptitude

2）安装上面提到的两个依赖软件包

sudo aptitude install ros-melodic-simulators ros-melodic-urdf-sim-tutorial 

3）安装ROS-melodic

sudo apt-get install ros-melodic-desktop-full

2、catkin_make功能包未找到moveit_core

Could NOT find moveit_core (missing: moveit_core_DIR)
– Could not find the required component ‘moveit_core’. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.

重新安装moveit：https://blog.csdn/weixin_47266712/article/details/124765684?spm=1001.2014.3001.5501

3、catkin_make功能包没有moveit_visual_tools

Could not find a package configuration file provided by
“moveit_visual_tools” with any of the following names:

moveit_visual_toolsConfig.cmake
moveit_visual_tools-config.cmake

解决方法：

sudo apt-get install ros-melodic-moveit-visual-tools

总结：绝对绝对不要使用sudo apt-get remove cmake卸载cmake，哭死！！！
