Source workspace gets a directory not found error

[wyd0817]

I can run some demos, like turtlesim, but when I source my workspace (source/install.setup.bash), I get the following error

/Users/wyd/miniforge3/envs/ros_env/local_setup.bash:.:11: no such file or directory: /Users/wyd/colcon_ws/local_setup.sh
not found: "/Users/wyd/colcon_ws/local_setup.bash"

ROS_DISTRO=humble
ROS_ETC_DIR=/Users/wyd/miniforge3/envs/ros_env/etc/ros
ROS_LOCALHOST_ONLY=0
ROS_OS_OVERRIDE=conda:osx

[Tobias-Fischer]

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

[wyd0817]

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.

[Tobias-Fischer]

What is contained in your colcon_ws?

[wyd0817]

There is only one ros_tcp_endpoint open source library.

[Tobias-Fischer]

Can you list all files in the colcon_ws?

[wyd0817]

Sure, here's a list of colcon_ws:

[Tobias-Fischer]

Can you try sourcing the zsh?

[wyd0817]

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

[Tobias-Fischer]

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

[wyd0817]

The unfortunate news, the result is the same.

[Tobias-Fischer]

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.

[wyd0817]

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.
