我想开始使用Ruby + Qt4。我已经下载了
$yum list qt* | less

然后我创建了新的qt项目并将其转换为ruby代码
$rbuic4 -x example.ui -o example.rb
然后我尝试编译example.rb
$ruby example.rb
并出现以下错误：
/home/n/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- Qt4 (LoadError)
from /home/n/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from example.rb:10:in `<main>'
我该如何解决这个问题？

您要找的包是ruby-qt。 $yum list qt* | less无法找到ruby-qt。无论如何，所有ruby-qt二进制包都已过时。像卡尔建议的那样做sudo gem install qtbindings。它将从维护的ruby-qt源代码库进行编译。 qtbindings主页位于https://github.com/ryanmelt/qtbindings/。

尝试gem install qtbindings
并在example.rb require 'Qt'
