ROS Installation Notes¶

These ROS installation notes are only useful if the default installation does not work for you (for instance, you are running on an older version of Ubuntu or Debian).

If the packages python3-catkin-tools and python3-yaml are available for your distribution, install them, and that should be sufficient. In this case you’re ready to read the ROS + MORSE tutorial.

Otherwise, follow these steps to install them manually:

Install ROS and run sudo rosdep init and rosdep update as explained in the installation wiki
Install Python 3 using your system package manager (available in Ubuntu >= 11.04) or manually from the source, and make sure your $PYTHONPATH variable includes the Python 3 libraries:
```
sudo apt-get install python3-dev
```
Install PyYAML with Python 3 support:
```
sudo apt-get install python3-yaml
```
or get it via pip the sources from http://pyyaml.org and build it using python3:
```
pip3 install pyyaml
```
Install catkin with Python 3 support:
```
pip3 install catkin_pkg rospkg
```
Open a terminal and check if everything is correctly set. Therefore, open a terminal and type:

morse check

If successful, the following line will be printed after some other information about your configuration:

* Your environment is correctly setup to run MORSE.

Now you can start having fun with MORSE and ROS! For example, start reading the ROS + MORSE tutorial.
