Hello,

Im on a mac and trying to update ruby. I update rails with the command:

sudo gem update rails --include-dependencies

and wondering if there is some sort of similar command for ruby.

Also, if I update ruby will it mess up my gems? Will I have to  
reinstall them?

Thanks in advance.

Great idea, but alas, no.

You should not have to reinstall your gems. However, if you get funny  
errors, then that would be the first thing to do (especially with gems  
that have native extensions).

As for the other part of your question, you really want to do a Google  
search. It will give you a native installer as the first link  
returned:

If that’s not your style, then try the DarwinPorts or Fink package  
managers.

You can always download the source code and install your own Ruby.

Thanks. I installed from source and everything worked out well.
