如何安装和运行python的qt-designer

Question

我对ubuntu很陌生，我输入了以下命令sudo apt-get install python-pyqt和sudo apt-get install qt-designer。

这两个命令都成功地执行了，但我无法弄清楚如何启动qt-designer程序。

Answer 1

与sudo apt-get install python-qt4 qt4-designer一起工作。

如果您使用apt-cache search qt | grep designer搜索它，您可以找到它：

libqt4-designer - Qt 4 designer module
libqt4-designer-dbg - Qt 4 designer library debugging symbols
qt4-designer - graphical designer for Qt 4 applications
kdesignerplugin - Integration of KF5 widgets in Qt Designer/Creator
kdesignerplugin-data - Integration of KF5 widgets in Qt Designer/Creator
kgendesignerplugin - Integration of KF5 widgets in Qt Designer/Creator
libopenrpt-dev - graphical SQL report writer, designer and rendering engine (development)
libopenrpt1v5 - graphical SQL report writer, designer and rendering library
libqscintilla2-designer - Qt4 Designer plugin for QScintilla 2
libqscintilla2-designer-dbg - Qt4 Designer plugin for QScintilla 2 (debug)
libqt5designer5 - Qt 5 designer module
libqt5designercomponents5 - Qt 5 Designer components module
libqt5scintilla2-designer - Qt5 Designer plugin for QScintilla 2
libqt5scintilla2-designer-dbg - Qt5 Designer plugin for QScintilla 2 (debug)
libqxt-designer0 - LibQxt extensions to Qt Designer
openrpt - graphical SQL report writer, designer and rendering engine

并搜索有关apt-cache show qt4-designer包的更多信息。

Answer 2

考虑到包名确实发生了巨大的变化，Ubuntu 20.04的过程现在是：

sudo apt-get install qttools5-dev-tools
sudo apt-get install qttools5-dev

然后，Qt作为designer安装，并且也在“开始”菜单中。

在终端上键入

designer-qt4

或者如果路径中没有包含/usr/bin：

/usr/bin/designer-qt4
