我在启动凉亭后尝试运行 rosrun，但出现以下错误，如图所示：

[rosrun] Couldn't find executable named sensor_data_listerner.py below /home/sk/catkin_ws/src/testbot_description

当我运行命令时：rosrun testbot_description sensor_data_listerner.py

我尝试使用source ~/catkin_ws/devel/setup.bash，但仍然无法使用

我已经使 phyton 文件可执行，但仍然无法运行。

希望有人可以帮助我

我的 CMakeLists 文件如图所示，但是当我尝试构建文件时出现错误：

cmake_minimum_required(VERSION 2.8.3)

## Declare ROS messages, services and actions ##
################################################

## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
##   * add a build_depend tag for "message_generation"
##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
##   * If MSG_DEP_SET isn't empty the following dependency has been pulled in
##     but can be declared for certainty nonetheless:
##     * add a run_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
##   * add "message_generation" and every package in MSG_DEP_SET to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * add "message_runtime" and every package in MSG_DEP_SET to
##     catkin_package(CATKIN_DEPENDS ...)
##   * uncomment the add_*_files sections below as needed
##     and list every .msg/.srv/.action file to be processed
##   * uncomment the generate_messages entry below
##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)

## Generate messages in the 'msg' folder
# add_message_files(
#   FILES
#   Message1.msg
#   Message2.msg
# )

## Generate services in the 'srv' folder
# add_service_files(
#   FILES
#   Service1.srv
#   Service2.srv
# )

## Generate actions in the 'action' folder
# add_action_files(
#   FILES
#   Action1.action
#   Action2.action
# )

## Generate added messages and services with any dependencies listed here
generate_messages(
  DEPENDENCIES
  std_msgs  # Or other packages containing msgs
)

################################################
## Declare ROS dynamic reconfigure parameters ##
################################################

## To declare and build dynamic reconfigure parameters within this
## package, follow these steps:
## * In the file package.xml:
##   * add a build_depend and a run_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
##   * add "dynamic_reconfigure" to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * uncomment the "generate_dynamic_reconfigure_options" section below
##     and list every .cfg file to be processed

## Declare a C++ library

## Rename C++ executable without prefix
## The above recommended prefix causes long target names, the following renames the
## target back to the shorter version for ease of user use
## e.g. "rosrun someones_pkg node" instead of "rosrun someones_pkg someones_pkg_node"
# set_target_properties(${PROJECT_NAME}_node PROPERTIES OUTPUT_NAME node PREFIX "")

## Add cmake target dependencies of the executable

我有如图所示的错误：

  • CMake 错误是由于“ inlcude ”文件夹不存在相对于“ /home/sk/catkin_ws/src/testbot_description”

    这就是错误消息所说的：

    catkin_package() include dir 'include' does not exist relative to
'/home/sk/catkin_ws/src/testbot_description'

    因此，要解决此问题，请在 /home/sk/catkin_ws/src/testbot_description 内创建文件夹包含或删除包含命令，如下所示：

    catkin_package(
LIBRARIES testbot_description
CATKIN_DEPENDS
urdf
tf
roscpp
rospy
std_msgs
geometry_msgs
sensor_msgs
DEPENDS system_lib

    )

  • 让它运行你的python脚本

    将您的 python 脚本放在 /home/sk/catkin_ws/src/testbot_description/ scripts文件夹中，并确保该文件具有执行权限。

  • 如果要运行启动文件，请将其添加到启动文件中

    <node pkg="testbot_description" type="sensor_data_listerner.py" 
              name="testbot_description" respawn="true">
</node>

  • 或者像您尝试使用 rosrun 一样使用

     rosrun testbot_description sensor_data_listerner.py
