[ROS] ImportError: No module named test_tutorials.srv的解决办法

生活所迫开始学ros

跟着教程一步一步做下来,其中

add_executable(add_two_ints_server src/add_two_ints_server.cpp)
target_link_libraries(add_two_ints_server ${catkin_LIBRARIES})
add_dependencies(add_two_ints_server test_tutorials_gencpp)
add_executable(add_two_ints_client src/add_two_ints_client.cpp)
target_link_libraries(add_two_ints_client ${catkin_LIBRARIES})
add_dependencies(add_two_ints_client test_tutorials_gencpp)

这一步报错，因为python下根本找不到那两个cpp文件 不太清楚教程里为什么要这么写 于是没有添加

反复确定了CMakeLists和package都是对的 但还是报错

~/catkin_ws$ rosrun test_tutorials add_two_ints_client.py
Traceback (most recent call last):
  File "/home/ann/catkin_ws/src/test_tutorials/src/add_two_ints_client.py", line 6, in 
    from test_tutorials.srv import *
ImportError: No module named test_tutorials.srv

解决办法：

在运行catkin_make之后 运行以下命令

~/catkin_ws$ source ~/catkin_ws/devel/setup.bash
