I was trying to follow this [tutorial][1]. Then when I got to this part node jsctags/bin/jsctags --sort=yes --locals tst.js I got the following warning message. > The "sys" module is now called "util". It should have a similar > interface. I'm doing this in OSX. First I tried the package and then I tried installing from source. I still get the same message. What does this mean? What can I do about it?
