I've updated your comment to have the code in the right format.
The colcon build seems to fail on a package called CFlib, which is the Crazyflie python library I assume? If the crazyflie-lib-python is in there, that is not setup to be a ROS package at all.
If you want the latest cflib build from source, you'll need to clone the repository in a completely different directory outside of the ROS workspace.
Hi, thanks for your reply. I have made modifications to the ROS workspace and resolved the issue.
When I follow https://imrclab.github.io/crazyswarm2/installation.html, 7. set up software-in-the-loop simulation (optional). I finished install swig,and make cf2_defconfig. But when I run make bindings_python, generate an error. If you could reply to me, I would greatly appreciate it。

Thank you again
Hi! I'm closing this issue since the problem was resolved.
