    background image "http://PATH_TO_IMAGE"
    a = stack :width => 360, :height => 200, :margin_left => 250, :margin_top => 200 do
        hover do
            a.clear { para "Some Text qwe qwe qwerty", :stroke => black }

我认为原则上你不能使用image作为background的参数。

我也不确定这是否是你想要达到的效果，但它显示了你做错了什么:

Shoes.app :width => 635, :height => 410 do
  a = stack :width => 360, :height => 200  do
    image "http://PATH_TO_IMAGE"
    hover do
         a.clear {para "Some Text qwe qwe qwerty", :stroke => black }
    end
    leave do
        a.clear {  image "http://PATH_TO_IMAGE" }
    end
  end
end
