ROS开发中的常见错误及解决方法-优快云博客

错误1 -- 在编译工作空间的时候,没有关闭conda环境

https://cloud.tencent.com/developer/ask/sof/128041https://cloud.tencent.com/developer/ask/sof/128041

ImportError: "from catkin_pkg.package import parse_package" failed: No module named 'catkin_pkg'
Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

错误2 -- 使用vscode编写代码时出现无法打开源文件ros/ros.h的错误,是因为没有配置包含路径

#include<sstream>
#include"ros/ros.h"
#include"std_msgs/String.h"

将下面这行include路径添加到包含路径中

/opt/ros/noetic/include/**

然后会生成.vscode里的一个配置文件

错误3 -- 无法用rosrun启动Publisher

admin1@admin1-System-Product-Name:~/catkin_ws$ rosrun learning_communication talker
[rospack] Error: package 'learning_communication' not found

在这之前先在终端中cd到工作空间,再设置环境变量(这种设置是当前终端的)

source ./devel/setup.bash

错误4 -- 添加消息生成依赖的功能包

错误示范:

  <run_depend>message_runtime</run_depend>

运行:

rosmsg show Person

结果:

Error(s):
- The manifest of package "learning_communication" (with format version 2) must not contain the following tags: run_depend
- Please replace <run_depend> tags with <exec_depend> tags.

根据提示更改package.xml中相应的消息:

  <exec_depend>message_runtime</exec_depend>

错误5 -- 学习到自定义话题时碰到了使用catkin_make命令编译的报错

CMake Error at /opt/ros/noetic/share/catkin/cmake/catkin_package.cmake:196 (message):
  catkin_package() the catkin package 'geometry_msgs' has been
  find_package()-ed but is not listed as a build dependency in the
  package.xml


CMake Error at /opt/ros/noetic/share/genmsg/cmake/genmsg-extras.cmake:197 (message):
  generate_messages() must be called before catkin_package() in project
  'learning_communication'


CMake Error at learning_communication/CMakeLists.txt:178 (add_dependencies):
  The dependency target "learning_communication_generate_messagess_cpp" of
  target "listener" does not exist.


CMake Error at learning_communication/CMakeLists.txt:173 (add_dependencies):

  target "talker" does not exist.

第一个错误参考

按照提示package.xml中没有geometry_msgs,添加上就行了:

  <build_depend>geometry_msgs</build_depend>
  <exec_depend>geometry_msgs</exec_depend>

第二个错误参考

按照提示将这两个函数的顺序颠倒一下(书上这几个函数的顺序并不对)

后面两个错误参考(这个错误还没有具体搞懂,直接往下搞!)
