Looks like you ran "ri" with some other user (probably root) and it
created a directory in your ".ri" directory that you cannot read.  You
need to either fix the permissions here:

  /Users/erik_mbp/.ri/cache/.doc_dirs

Look at the "chown" command.

Or just rm your ".ri" directory and like rdoc rebuild it.
