bash: ../../../devel/setup.bash: No such file or directory

Hi,

I'm following these steps to install Crazyswarm.

$ cd crazyswarm
$ ./buildSimOnly.sh
$ cd ros_ws/src/crazyswarm/scripts
$ source ../../../devel/setup.bash

However, after I execute the last command, it gave me this error, " bash: ../../../devel/setup.bash: No such file or directory
"
I checked and there is indeed no folder called devel under src. I was wondering what could be wrong with my environment? Thanks,

you need to run the full build.sh if you want to use ROS.
