Could not find executable running image_view from rosrun

Question

I've been using image_view to see the contents of image topics for some time, but I encountered a problem and I have no idea what the cause is. Here's what I get when trying to check an image topic:

Command I typed:

rosrun image_view image_view image:=/...(topic)

Terminal output:

[rosrun] Couldn't find executable named image_view below /opt/ros/hydro/share/image_view

[rosrun] Found the following, but they're either not files, or not executable:

[rosrun] /opt/ros/hydro/share/image_view

It shouldn't be a source problem. Many other programs can run normaly.

I would really appreciate your help. Thanks!

Answer 1

If you installed it using Debian try deleting it and reinstalling it, maybe it will be the fastest way to solve your problem.

sudo apt-get remove ros-hydro-image-view

and then

sudo apt-get install ros-hydro-image-view

Otherwise delete everything called image_view manually and reinstall it using apt-get.

Reinstalling it is indeed the fastest way to solve the problem. Thank you

Answer 2

try the Qt GUI plugin version of image_view.

If you're using hydro:

sudo apt-get install ros-hydro-rqt-image-view

otherwise, don't forget to replace the hydro with the ros distro you're using.

Then run the executable node:

rosrun rqt_image_view rqt_image_view

At the top left corner, you can search for the image topic to listen.

For more details: rqt_image_view
