如何使用Instant Rails在Windows中升级我的Ruby版本？

Question

If I'm using Instant Rails, how do I upgrade my Ruby version from 1.8.6 to 1.9.* which they say runs faster in Windows? What's the necessary Instant Rails console command? Thanks.

Here's an alternative to consider.

You could just install ruby 1.9.2 (1.9.1 segfaults with Rails3 and isn't recommended ... make sure to install it to a different folder like c:\\ruby192 or something) then use pik http://github.com/vertiginous/pik to switch the ruby version you're running.

I bet that would work just fine. Keep in mind that you'd have to install all your gems again though.
