I work with a turtlebot3 burger. In the instructions, when I install packages, http://emanual.robotis.com/docs/en/pl... (16.1.4)

mkdir -p ~/turtlebot3_ws/src

cd ~/turtlebot3_ws

wget https://raw.githubusercontent.com/ROBOTIS-GIT/turtlebot3/ros2/turtlebot3.repos

vcs import src < turtlebot3.repos

colcon build --symlink-install

the following error occurs:

CMake Error at CMakeLists.txt:19 (find_package):
  By not providing "Findgazebo_ros_pkgs.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "gazebo_ros_pkgs", but CMake did not find one.

  Could not find a package configuration file provided by "gazebo_ros_pkgs"
  with any of the following names:

    gazebo_ros_pkgsConfig.cmake
    gazebo_ros_pkgs-config.cmake

  Add the installation prefix of "gazebo_ros_pkgs" to CMAKE_PREFIX_PATH or
  set "gazebo_ros_pkgs_DIR" to a directory containing one of the above files.
  If "gazebo_ros_pkgs" provides a separate development package or SDK, be
  sure it has been installed.

That’s the classic “you didn’t install that package” error. Make sure to install it and/or run rosdep.

You must install the gazebo-ros package

sudo apt-get install ros-melodic-gazebo-ros

change melodic for your ros version

The comments to #q360774 are what helped me: gazebo_ros_pkgs has to be installed from source:

  1. Make sure to have Gazebo installed.
  2. Go to workspace src and then git clone https://github.com/ros-simulation/gazebo_ros_pkgs.git -b ros2 (this clones branch ros2)
  3. sudo rosdep update followed by rosdep check --from-paths . --ignore-src --rosdistro $ROS_DISTRO -y. If all goes well you should see "All system dependencies have been satisfied".
  4. Move one level above src and then finally colcon build. Don't forget to source this workspace.

It looks like you may not have sourced the environment script as described in the official install docs linked by the ROBOTIS guide https://index.ros.org/doc/ros2/Instal...

I had sourced it but still, it shows the same error. I have been following ros2 setup on turtlebot3 https://emanual.robotis.com/docs/en/p...

Hi, you have to install all of the necessary packages needed for ros2, and then clone the repositories with the commands

wget https://raw.githubusercontent.com/ROBOTIS-GIT/turtlebot3/ros2/turtlebot3.repos
vcs import src < turtlebot3.repos
colcon build --symlink-install

That should get you to compile the packages. If you want a step by step explanation, I made this video that can help:
