I was trying to run ROSSkill. When Launch roscore on your PC:

Then, I use the $ rosrun rosserial_python serial_node.py tcp in a new terminal, and the error is as follows:

The ROS system and rosserial is installed on my PC. My system is Ubuntu 14.04, ROS is 'indigo’
Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty

It looks like your rosserial_python is not recognized by your system. Please check if you complete all the steps in rosserial’s Installing documentation.

Did you run this command after you install rosserial?
source <ws>/install/setup.bash
PS: It might need to be run every time after you start a new terminal to make rosserial able to be found.

Thanks for your helping, this is really a happy thing!

I run this command $ source <ws>/install/setup.bash before run ‘$ rosrun rosserial_python serial_node.py tcp’. Then, the problem is solved.

And I also tried to run ‘$ rosrun rosserial_python serial_node.py tcp’ directly, it did occurred the same errors. That means I should to run that command everytime.

Thus, I run this command in a new terminal$ echo "source catkin_ws/install/setup.bash" >> ~/.bashrc. Then, I won’t have to run this command everytime.
