什么是Qt5在14.04的开发包
我想在我的台式机上构建一个Qt5示例。 我安装了qt5-default和qtdeclarative5-dev ，但我仍然收到此错误：
Project ERROR: Unknown module(s) in QT: quick qml
应该安装哪个软件包进行编译？ 在Qt4时代它只是libqt4-dev
你需要安装
qtdeclarative5-dev
Ubuntu上提供的所有Qt5开发包的列表 。

标题的答案是：
sudo apt-get install qtbase5-dev
但是对于您的具体问题，上面的答案是正确的。
sudo apt-get install qtdeclarative5-dev qml-module-qtquick-controls
通过::validation安装
qtchooser -print-env
输出可能类似如下（基于您的Ubuntu版本可用的包）：
QT_SELECT="default" QTTOOLDIR="/usr/lib/x86_64-linux-gnu/qt5/bin" QTLIBDIR="/usr/lib/x86_64-linux-gnu"
