(笔记)ROS2 colcon build报错：ModuleNotFoundError: No module named ‘catkin_pkg‘

 

在使用ROS2时，使用colcon build编译时，报错如下：

 1 Starting >>> fishbot_navigation2
 2 --- stderr: fishbot_navigation2                         
 3 Traceback (most recent call last):
 4   File "/opt/ros/foxy/share/ament_cmake_core/cmake/core/package_xml_2_cmake.py", line 21, in <module>
 5     from catkin_pkg.package import parse_package_string
 6 ModuleNotFoundError: No module named 'catkin_pkg'
 7 CMake Error at /opt/ros/foxy/share/ament_cmake_core/cmake/core/ament_package_xml.cmake:94 (message):

22 Summary: 0 packages finished [0.42s]
23   1 package failed: fishbot_navigation2
24   1 package had stderr output: fishbot_navigation2

 

解决方法：

pip3 install catkin_pkg

 

 

再次colcon build，成功了！因为此问题困住了好长时间，以前同样的方式没有任何问题，但突然新的工程都没法编译，而唯一的变化就是最近新安装了“conda”，它应该就是这个罪魁祸首了！
