所以我正在尝试从http://p2-dev.pdt-extensions.org安装Twig插件，但收到此消息：
Cannot complete the install because one or more required items could not be found.
Software being installed: Twig Editor Feature 1.0.13.201309142024 (com.dubture.twig.feature.feature.group 1.0.13.201309142024)
Missing requirement: com.dubture.twig.core 1.0.13.201309142024 (com.dubture.twig.core 1.0.13.201309142024) requires 'bundle org.eclipse.wst.sse.core 0.0.0' but it could not be found
Cannot satisfy dependency:

To: com.dubture.twig.core [1.0.13.201309142024]
这个问题有解决方法吗？
