Lua 图像错误

Question

我已经根据这个安装了 lua 镜像 - link .我还使用 luajit -limage -e "image.test()" 测试了我的安装它说 0 个错误和 0 个警告。另外，当我尝试

> require 'image'
> l = image.lena()

没有错误。但是，当我尝试时 image.display(l) ，我收到以下错误:

/home/srilatha/torch/install/share/lua/5.1/trepl/init.lua:384: module 'qt' not found:No LuaRocks module found for qt

我的手电筒运行正常，所以我不知道 qt 会出现什么问题.我怎样才能解决这个问题？

你有没有偶然读到这篇文章？

https://github.com/torch/image/blob/master/doc/gui.md

image.display 等功能只能通过 qlua Lua 解释器访问。

从 LuaJit 调用该函数将导致您面临的错误。
