According to ros wiki, to set up environment, I typed
echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
source ~/.bashrc
The error is
/opt/ros/kinetic/setup.bash:.:8: no such file or directory: /home/pikashun/setup.sh
In ~/.bashrc
file, there is the source /opt/ros/kinetic/setup.bash
line.
I use Ubuntu on WSL. How can I improve?
Thank you!
I had the exact same issue. The problem is not due to setup.bash
either ~/.bashrc
but the shell that you are using. It turned out that you may be using a different shell than bash
(ie, zsh
). When you are executing the setup.bash
of ROS, zsh
interprets the following command (whici is in /opt/ros/kinetic/setup.bash
) differently:
_CATKIN_SETUP_DIR=$(builtin cd "`dirname "${BASH_SOURCE[0]}"`" > /dev/null && pwd)
It is setting the _CATKIN_SETUP_DIR
to your user directory. That is why you are getting error, cause you using the wrong path: /home/user/setup.bash
instead of /opt/ros/kinetic/setup.bash
To check whether this is the issue of your problem, you can check the shell that you are using by execute the following in the terminal:
echo $0; echo $SHELL
It may return something like:
zsh
/bin/zsh
To switch from zsh
to bash
, use:
exec bash
Once done this, you can use source without any problem.
And to switch back to your previous shell (assuming that is zsh
), just use:
exec zsh
The file /opt/ros/kinetic/setup.bash
does nothing but loading /opt/ros/kinetic/setup.sh
from the same directory. I might be that you are not running bash
( check which terminal you run ), or that WSL has some different behavoiour than expected. However, your can just alter your append command like so:
echo "source /opt/ros/kinetic/setup.sh" >> ~/.bashrc
or in your case, since the entry exists already in your ~/.bashrc
, edit the line source /opt/ros/kinetic/setup.bash
to source /opt/ros/kinetic/setup.sh
The packages or files were not actually downloaded from the " http://wiki.ros.org/melodic/Installation/Ubuntu ". To overcome this error first open terminal
check your directory pwd
. If your directory is like /home/'Your PC Name' it won't actually work.
Change the directory : Type cd /
Continue the installation process from start which mentioned in " http://wiki.ros.org/melodic/Installation/Ubuntu "
melodic can change to kinetic or other version if you wish
have you installed kinetic ? you could check the path by
/opt/ros/kinetic
do you see setup.bash
