catkinConfig.cmake:83 (find_package): Could not

在进行ROS编译 catkin_make 时，缺少数据包文件 std_msgs

bruce@bruce-desktop:~/catkin_ws$ catkin_make

出现错误

CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "std-msgs" with any
  of the following names:

    std-msgsConfig.cmake
    std-msgs-config.cmake

  Add the installation prefix of "std-msgs" to CMAKE_PREFIX_PATH or set
  "std-msgs_DIR" to a directory containing one of the above files.  If
  "std-msgs" provides a separate development package or SDK, be sure it has
  been installed.

Makefile:320: recipe for target 'cmake_check_build_system' failed

Invoking "make cmake_check_build_system" failed

因为缺少文件，（亲测），

从新安装一遍ROS，

不必卸载原来的ROS，再编译，问题解决。

还有遇见的一些主要问题：

问题1：

bruce@bruce-desktop:~$ sudo rosdep init


ERROR: default sources list file already exists:
	/etc/ros/rosdep/sources.list.d/20-default.list
Please delete if you wish to re-initialize

按要求删除文件

bruce@bruce-desktop:~$ su root
Password: 

root@bruce-desktop:/home/bruce# pwd
/home/bruce

root@bruce-desktop:/# cd  /etc/ros/rosdep/sources.list.d/
root@bruce-desktop:/etc/ros/rosdep/sources.list.d# ls -l
total 4
-rw-r--r-- 1 root root 588 11月 25 19:11 20-default.list
root@bruce-desktop:/etc/ros/rosdep/sources.list.d# rm 20-default.list
root@bruce-desktop:/etc/ros/rosdep/sources.list.d#

问题2：

再次创建 test_pkg文件时，出现一些错误，按照提示，删除相应文件即可。

bruce@bruce-desktop:~/catkin_ws$ cd src
bruce@bruce-desktop:~/catkin_ws/src$ catkin_create_pkg test_pkg std_msgs rospy roscpp
