我第一次遇到这个问题，我不明白为什么...当我想创建一个 catkin 工作区时，我会创建一个新目录并执行catkin_make或catkin init，实际上工作区始终是我的主目录，而不是我创建的新工作区。因此，在我的主目录上也创建了一个build和devel目录。你知道我在这里错过了什么吗？非常感谢您的帮助
emeric@emeric-desktop:~$ cd catkin_planning_ws/
emeric@emeric-desktop:~/catkin_planning_ws$ ls
src
emeric@emeric-desktop:~/catkin_planning_ws$ catkin init

我遇到了完全相同的问题，这是解决方案：
1. cd #go to home dir
2. ls -la | grep catkin #cheak if there is a dir named *.catkin_tools*, that's the problem!!!
3. rm -r .catkin_tools
做！希望这也适用于您的情况。
