You can delete your old catkin workspace folder and remove possible references for its previous devel/setup.bash
.
The command catkin clean
only clean the files generated by catkin build.
A catkin workspace is a folder. It contains a src
folder with some ROS packages inside. There can exist multiple workspaces with different names, but only one is usually activated.
To activate a workspace, you need to init and build it first, generating the folders devel
and build
. Then, you need to source the setup.bash
.
If you want to know which workspace is activated at the moment, you can check the first folder from command
echo $ROS_PACKAGE_PATH
You can find examples of workflow at catkin-tools website. It seems complicated at first, but soon you will get the hang of it ;)
