It is likely that the instructions you are following have omitted to mention some non-standard prerequisites that must be installed first.

I don't get the meaning of the message -bash: fetch: command not found

The command shell, bash, is telling you that it cannot find a command named "fetch" or it is reporting an error returned by a fetch command it did find.

This general sort of error message can occur when the command does not exist or when it is the name of a program that is not in the current $PATH.
