如何安装和运行 qt-designer for python

Question

我是 ubuntu 新手，我输入了以下命令 sudo apt-get install python-pyqt和sudo apt-get install qt-designer。
两个命令都成功执行，但我不知道如何启动该qt-designer程序。

Answer 1

考虑到包名称戏剧性地更改后，Ubuntu 20.04 的流程现在是：

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

然后，Qt Designer 就安装为designer，并且也在开始菜单中。
