Installing gems - what does "INFO: `gem install -y` is now default and will be removed" mean

When I install a new gem, I see this message:

"INFO: gem install -y is now default and will be开发者_开发百科 removed"

What does it mean? My quick Google search didn't turn up anything useful.

The -y option tells gem to install dependencies when installing the named gem. This is now the default action, so you don't need to worry about specifying the -y option any more. Eventually, the developers of gem will remove the option -y.

So in short, just use gem install instead, and ignore the -y.

It means that RubyGems will automatically install any required dependent gems.
