如何在zerobrane studio中显示RGB图像？

在Ubuntu 14.04中，如果我在命令行中调用的qlua解释器中运行以下代码（有或没有第一行），它会显示Lena图像：

require('mobdebug').start()    -- for image.display()
require 'image'
image.display( image.lena() )

我可以通过gnuplot显示灰度图像：

require 'gnuplot'
require 'image'
M = image.rgb2y( image.lena() )
P = M[{1,{},{}}]
gnuplot.imagesc(P)

但是，如果我将Zerobrane Studio v1.30解释器设置为QLua-LuaJIT（没有“qlua”解释器），然后运行它，我会收到以下错误：
