安装 ruby​​-qml - 错误：无法构建 libqmlbind - 缺少什么？

Question

我正在尝试在 Ubuntu 15.10 (Wily) 上安装 ruby-qml。

我之前检查过先决条件。网站上没有任何关于 Linux 的文档。我检查了一些常见的嫌疑人（build-essential bison openssl libreadline5 libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-开发 libglu1-mesa-dev)。检查/安装libqt5qml5 libqt5quick5 qtdeclarative5-dev qt5-default 修复了一些早期的问题。

此时，当运行 Gem 安装程序时，它会停止并显示错误和以下输出：

:#> gem install qml
Building native extensions.  This could take a while...
ERROR:  Error installing qml:
        ERROR: Failed to build gem native extension.

Gem files will remain installed in /var/lib/gems/2.1.0/gems/qml-1.0.2 for inspection.
Results logged to /var/lib/gems/2.1.0/extensions/x86_64-linux/2.1.0/qml-1.0.2/gem_make.out

这里有什么问题？我该如何解决？
