Managing System Dependencies

Occasionally files depend on other files. Here we attempt to solve those dependencies.

1) In a new terminal, navigate to the turtlesim folder:

roscd turtlesim

2) Use rosdep install [package] to download the dependencies for the specified package:

rosdep install turtlesim

• If you get an Error:

You may get "Error: ... Please run" message. If that is the case, it will list the commands it wants you to run. Copy those commands and paste them into the current terminal. Then rerun:

rosdep install turtlesim

This may then print "All required rosdeps installed successfully" or the output if installing the dependencies.

• If you get "All required rosdeps installed successfully"

The dependencies were all installed successfully.
