I am trying to install ruby to a specific directory, a USB stick, so I can move the usb back and forth without having to install ruby on each machine I get to (I need ruby 2.0+). How can I do this?
I have been looking after stuff like setting RVM install directory and so forth, with no luck. The closest I found was this description telling me how to move the entire RVM install, which I don't want. I just want a simple ruby version on a usb stick.
On windows this was very easy: Run RubyInstaller, and point it to the USB. On OSx, well, that's another story.
How can I achieve this?
