Thanks for your reply, I found the mistake. I made a particularly basic mistake, I was wrongly sourcing the .bash file in mac os, the correct one should be the .zsh file. That's it, it was fixed.

Can you please provide the exact commands that you run, and some way that we can easily replicate the error?

Thank you for your quick response.
I ran the following command.
source/install.setup.bash
Here is a screenshot of what I did.
BTW, I was able to successfully compile the ros2 project.

There is only one ros_tcp_endpoint open source library.

Can you try sourcing the zsh?

I source zsh, then my conda environment becomes (base), here is an output.

Can you clean your colcon ws, then in a new terminal activate your robostack environment, then build the ws and try again?

The unfortunate news, the result is the same.

I cannot replicate your issue. Please:
- create a new robostack environment from scratch as written in the README and activate it
- install colcon:
mamba install colcon-ros - create a new colcon_ws with your package:
mkdir -p ~/colcon_ws_new/src && git clone https://github.com/Unity-Technologies/ROS-TCP-Endpoint - checkout the correct branch:
cd ROS-TCP-Endpoint; git checkout main-ros2 cd ~/colcon_ws_new- build your workspace:
colcon build --symlink-install - source the workspace:
. install/setup.sh(see https://docs.ros.org/en/foxy/Tutorials/Beginner-Client-Libraries/Colcon-Tutorial.html) - run your package:
ros2 launch ros_tcp_endpoint endpoint.py
These exact steps worked for me just then. Feel free to reopen if you still have issues.
