/home/youruser/catkin_ws/src:/opt/ros/kinetic/share: There is no such file or directory
I also have. problem:
/home/youruser/catkin_ws/src:/opt/ros/noetic/share: There is no such file or directory
- OS ubuntu 20.04
- ROS noetic: installation site
The steps I have taken:
- Installing ROS
Environment Management: Introduced commands
$ printenv | grep ROS $ source /opt/ros/<distro>/setup.bash $ source /opt/ros/kinetic/setup.bash
Creating the ROS workspace: catkin section, entered commands:
$ mkdir -p ~/catkin_ws/src $ cd ~/catkin_ws/ $ catkin_make $ catkin_make -DPYTHON_EXECUTABLE=/usr/bin/python3 $ source devel/setup.bash $ echo $ROS_PACKAGE_PATH /home/youruser/catkin_ws/src:/opt/ros/kinetic/share
Error:
/home/youruser/catkin_ws/src:/opt/ros/noetic/share: There is no such file or directory

You are on the right track and only need minor assistance. Please read below:
- It seems you are getting confused about the
source
command. First of all, because you are in Ubuntu 20.04, you should use ROS Noetic. Therefore, please replace the textkinetic
withnoetic
in every command. Next, after installing ROS Noetic, you should be able to source it. For example, you can see ROS-related environment variables after sourcing it, as shown below:
ravi@dell:~$ printenv | grep ROS ravi@dell:~$ source /opt/ros/noetic/setup.bash ravi@dell:~$ printenv | grep ROS ROS_VERSION=1 ROS_PYTHON_VERSION=3 ROS_PACKAGE_PATH=/opt/ros/noetic/share ROSLISP_PACKAGE_DIRECTORIES= ROS_ETC_DIR=/opt/ros/noetic/etc/ros ROS_MASTER_URI=http://localhost:11311 ROS_ROOT=/opt/ros/noetic/share/ros ROS_DISTRO=noetic
Most importantly, you can notice that ROS_DISTRO
is set to noetic
and ROS_PACKAGE_PATH
is set to the installation directory.
3. You are good to go if you see a similar output on your side. Now, you can create a workspace as you were doing before. Please see the below commands:
ravi@dell:~$ mkdir -p ~/catkin_ws/src
ravi@dell:~$ cd catkin_ws/
We have created an empty workspace. Now, we should compile it. Before executing
catkin_make
, do not forget tosource
your ROS installation as shown below:ravi@dell:~/catkin_ws$ source /opt/ros/noetic/setup.bash ravi@dell:~/catkin_ws$ catkin_make Base path: /home/ravi/catkin_ws Source space: /home/ravi/catkin_ws/src Build space: /home/ravi/catkin_ws/build Devel space: /home/ravi/catkin_ws/devel Install space: /home/ravi/catkin_ws/install Creating symlink "/home/ravi/catkin_ws/src/CMakeLists.txt" pointing to "/opt/ros/noetic/share/catkin/cmake/toplevel.cmake" #### #### Running command: "cmake /home/ravi/catkin_ws/src -DCATKIN_DEVEL_PREFIX=/home/ravi/catkin_ws/devel -DCMAKE_INSTALL_PREFIX=/home/ravi/catkin_ws/install -G Unix Makefiles" in "/home/ravi/catkin_ws/build" #### -- The C compiler identification is GNU 9.4.0 -- The CXX compiler identification is GNU 9.4.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Using CATKIN_DEVEL_PREFIX: /home/ravi/catkin_ws/devel -- Using CMAKE_PREFIX_PATH: /opt/ros/noetic -- This workspace overlays: /opt/ros/noetic -- Found PythonInterp: /usr/bin/python3 (found suitable version "3.8.10", minimum required is "3") -- Using PYTHON_EXECUTABLE: /usr/bin/python3 -- Using Debian Python package layout -- Found PY_em: /usr/lib/python3/dist-packages/em.py -- Using empy: /usr/lib/python3/dist-packages/em.py -- Using CATKIN_ENABLE_TESTING: ON -- Call enable_testing() -- Using CATKIN_TEST_RESULTS_DIR: /home/ravi/catkin_ws/build/test_results -- Forcing gtest/gmock from source, though one was otherwise available. -- Found gtest sources under '/usr/src/googletest': gtests will be built -- Found gmock sources under '/usr/src/googletest': gmock will be built -- Found PythonInterp: /usr/bin/python3 (found version "3.8.10") -- Found Threads: TRUE -- Using Python nosetests: /usr/bin/nosetests3 -- catkin 0.8.10 -- BUILD_SHARED_LIBS is on -- BUILD_SHARED_LIBS is on -- Configuring done -- Generating done -- Build files have been written to: /home/ravi/catkin_ws/build #### #### Running command: "make -j16 -l16" in "/home/ravi/catkin_ws/build" ####
The compilation is done successfully. Now, in order to run any package (right now, we don't have any, nevertheless), first, we need to
source
the ROS installation file and thensource
the workspace file as shown below:ravi@dell:~/catkin_ws$ source /opt/ros/noetic/setup.bash ravi@dell:~/catkin_ws$ source devel/setup.bash
Finally, you can confirm that both of the above
source
commands worked well by looking into theROS_PACKAGE_PATH
environment variable as shown below:ravi@dell:~/catkin_ws$ printenv | grep ROS ROS_VERSION=1 ROS_PYTHON_VERSION=3 ROS_PACKAGE_PATH=/home/ravi/catkin_ws/src:/opt/ros/noetic/share ROSLISP_PACKAGE_DIRECTORIES=/home/ravi/catkin_ws/devel/share/common-lisp ROS_ETC_DIR=/opt/ros/noetic/etc/ros ROS_MASTER_URI=http://localhost:11311 ROS_ROOT=/opt/ros/noetic/share/ros ROS_DISTRO=noetic
Notice that ROS_PACKAGE_PATH
points to your workspace and the ROS Noetic installation directories.

I have done everything above, but when I try to execute the command:
$ echo $ROS_PACKAGE_PATH /home/youruser/catkin_ws/src:/opt/ros/kinetic/share
error is returned: /src:/opt/ros/kinetic/share: There is no such file or directory

Please format your code correctly because we can not see what the command is and what the output of your command is.
