rosserial on arm prosessor [closed]

edit

Hi I have a project where I use rosserial with an arduino, I have code that publishes messages from one arduino, connected to a pc, and another arduino that subscribes, connected to an Odroid XU3. I had to install rosserial on the Odroid using this method below due to the normal way not working with arm processors.

cd ~/
mkdir -p catkin_ws/src
cd catkin_ws/src/
catkin_init_workspace
cd ..
catkin_make
cd ~/catkin_ws/src/
git clone https://github.com/chuck-h/rosserial.git
cd rosserial/
git checkout hydro-devel
cd ~/catkin_ws
catkin_make install
rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0

When I run the program the terminal returns this error.

: No such file or directory

This error has really confused me due to the lack of information it provides, has anyone come across this before
