[Question] Windows supported?

[tan-wei]

• OS: WInsows 10
• Ruby: 2.5.5 x32

It fails after require 'lightio', error messages are shown below:

ArgumentError: unsupported backend:
from C:/Ruby25/lib/ruby/gems/2.5.0/gems/nio4r-2.3.1/lib/nio/selector.rb:17:in `initialize'
Caused by LoadError: cannot load such file -- lightio
from C:/Ruby25/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in `require'

Maybe I should set the backend in ENV just like

set LIGHTIO_BACKEND=epoll

How to set the backend with an available one? Thanks!

It seems that the only valid input for NIO::Selector.new is :ruby (a symbol but not a string). When I set LIGHTIO_BACKEND in ENV, it is always a string. For example, when I set LIGHTIO_BACKEND to ruby, it will also fail.
