我试图安装在Ubuntu20.04的口径,但它不会发射。我遵循了另一个问题(口径不再工作)的说明,但没有奏效。我就是这样安装的(5.20.0版):

我正在用Qt5.15.2用C++编写一个软件。我需要在Raspberry Pi 4上部署它,并在Raspberry上安装Qt和Qt5.15.2 (我知道我也可以进行交叉编译,但我会保留到以后)。当我试图从QtCreator运行该软件时,我会得到以下错误:

为了提供一些背景情况,这一切都是最近开始的,当我试图更新和/或重新安装我的AMD驱动程序(对于Radeon RX 560卡),但它不能完全完成。然而,我的系统仍然像往常一样工作。作为一个可能的修复,我也做了版本升级从焦点到Jammy,但自从我只能使用TTY,因为没有桌面或GUI似乎功能。

我正在用Qt做一点实验。我已经成功地写了一个小应用程序,它在我的Windows 8.1笔记本电脑上运行良好。现在,我安装了XCode和Qt,并将项目文件夹复制到我的MacBook中。这个应用程序在我的Mac上编译得很好,但当我不想通过Qt Creator运行它时,我得到了以下错误:

我试着在cmd中运行这个:

我正在编写python (3.9)应用程序,并希望使用pyinstaller分发可执行文件。我正在pipenv环境中运行opencv-contrib-python==4.5.4.60、opencv-python==4.5.4.60和numpy==1.21.4。

在运行cmake for 后,我得到了以下错误:
Could NOT find Qt5FontDatabaseSupport (missing:
Qt5FontDatabaseSupport_LIBRARY Qt5FontDatabaseSupport_INCLUDE_DIR) (found

在我的linux存储库中,我找不到任何具有该名称的包。
这是Qt QPA插件的依赖项之一,如CMakeLists.txt注释中所述。
我将Kubuntu 20.04与cmake 3.16和Qt5.12结合使用。
谢谢。
故事是,我用Python3.8、PyQt5和Postgres构建了一个Python软件,所以我试图创建一个容器来对所有这些东西进行对接,我正在考虑创建一个Dockerfile来创建一个用于python + pqt5的容器,另一个只用于Postgres的容器,然后使用docker-组合来链接所有的东西。
问题是,当我试图为PythonandPyQt5创建一个容器时,我将面临这个错误。
