Errors in setting up ROS tutorial workspace in "tf tutorials"

edit

Hi everyone,

I am learning ROS (ROS cturtle) from the tutorials. I got an error when setting up the ROS tutorial workspace in "tf/tutorials".

It asked me to:

Create a file named ~/tutorials.rosinstall with the following content:

- other: local-name: workspace

To overlay on cturtle:

rosinstall ~/tutorials /opt/ros/cturtle ~/tutorials.rosinstall

I got confused with the term "workspace". I assume i gotta replace it with my working directory. I put it like

 - other: local-name: ~/tutorials.

Then I run

 rosinstall ~/tutorials /opt/ros/cturtle ~/tutorials.rosinstall

It prompts me an error:

rosinstall operating on /home/vincent/tutorials from specifications in rosinstall files  /home/vincent/tutorials/.rosinstall, /opt/ros/cturtle, /home/vincent/tutorials.rosinstall processing config_uri /opt/ros/cturtle ahhhhhhhh, yaml parse error: mapping values are not allowed here   in "/home/vincent/tutorials.rosinstall", line 3, column 19 Usage: rosinstall PATH [<options> ...] [URI]... 

rosinstall: error: None

Deleting the space between "local-name" and "~/tutorials" in that command-line solved this error. But got another error:

rosinstall operating on /home/vincent/tutorials from specifications in rosinstall files  /home/vincent/tutorials/.rosinstall, /opt/ros/cturtle, /home/vincent/tutorials.rosinstall

TypeError: string indices must be integers, not str

And I also tried replacing "workspace" with "/opt/ros/cturtle/stack" or "/opt/ros/cturtle/ros" or "/opt/ros/cturtle". They gave basically the same errors.

Can someone help me out? Probably obvious to everyone else, please excuse my dumbness.-_-
