hello. im in execrise chapter 2 (manipulation moveit)  
when i try to source the files:

`source install/setup.bash`

i got this error:

```auto

ROS_DISTRO was set to 'foxy' before. Please make sure that the environment does not mix paths from different distributions.
ROS_DISTRO was set to 'noetic' before. Please make sure that the environment does not mix paths from differentdistributions.

```

can anyone help me to solve this?  
thank you very much.

**THIS IS NOT AN ERROR !!!**

It is just a **WARNING** that informs you that the **ROS\_DISTRO** environment variable was changed. And what the value was before.

I am assuming you are using ROS2. Please be aware that every time you want to execute a ROS2 package, you need to source ROS2 version by doing `source /opt/ros/foxy/setup.bash`. This will produce that warning message. It is to inform **YOU** (@Scotvers ) that the environment is now setup for ROS2.

Resetting the simulation will not solve this. As I said earlier, **THIS IS NOT A PROBLEM !!!**  
Resetting simulation is also not a solution.

At this point I am presuming that you have never worked on ROS2 environment - either through **ROS2 in 5 Days** course or by physical work in your own computer/laptop.

I would like to suggest that you take a quick glance at the **ROS2 Basics in 5 Days** course - either C++ or Python - whichever language you prefer - and understand the basic environment of ROS2. Please stop working on **ROS2 Manipulation** course for a short while. Come back to the course after taking a ROS2 refresher.

I did not mean to discourage you. Please do not mistake me.  
This is a very newbie mistake - which clearly shows that you had no prior experience in ROS2 environment.

Sincere Regards,  
Girish
