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!
