Impossible to launch rosbridge_tcp

edit

Hello, I'm trying to start the rosbridge_tcp.launch - file. But I always get to following error-messages. All other nodes in my workspace run successful. So the rosbridge_server is the only one that doesn't work. I'm using the packages lms1xx and other packages for a stereocamera too and they work fine. I installed ROS kinetic for Ubuntu 16.04 like described in ros-wiki installation.

previous procedure:

• installing Ubuntu 16.04 on pc
• installing ROS kinetic like described in ros-wiki
• also installing CUDA 9.1 Toolkit and ZED SDK
• set up ros catkin_ws-workspace like described in the ros-wiki
• copy the packages from the previus pc to the workspace of the new pc (rosbridge_suite, lms1xx, zed_wrapper, and other self implemented packages)
• added the lines described futher down to the .bashrc-file
• catkin_make of workspace
• sudo apt-get install ..... for all packages in the workspace
• rosdep install .... for all packages

-> I thought, that I did everything like it was on the previous pc

roslaunch rosbridge_server rosbridge_tcp.launch

I cloned the package from github and only added parameters for a timedelay, nothing else. Any ideas why it does not work and what I can do?
