无法加载QT环境
Unable to Load QT Environment
我完全不知所措，希望有人能提供帮助。我习惯了 Visual Studio 环境和设置，QT 对我来说是新的。我是 运行ning Linux Mint（debian 20.04）并安装了 qt5-default 和 qtcreator。 QT creator 第一次加载时没有问题，但是在关闭应用程序并重新启动系统后，它拒绝加载。我一直在寻找 google 和堆栈，我发现了一些类似的问题，但 none 到目前为止我找到的解决方案对我有用。尝试从终端 运行 qtcreator 呈现以下输出：

从输出来看，似乎有两个相互冲突的版本，但是，作为 QT 的新手，我不确定我如何或是否将其指向正确的版本。感谢您的帮助！
我们是否应该有很多行，例如：
qtcreator: /usr/lib/x86_64-linux-gnu/libQt5Gui.so.5: no version information available (required by qtcreator)
指向 Linux 文件系统的根 user 而不是 /home/user 表示我们已经安装了 Qt Creator（不是真正最新的 Qt 框架，甚至不是 Creator） sudo apt install qtcreator 作为较旧的 IDE 可能会派上用场，但除此之外没有太多，并且由于许多库软 link 重定向等而容易出现系统错误
首先将其从系统中清除：
sudo apt purge qtcreator
正如最初的发帖人所问，通过使用 Qt Maintenance Tool 完全删除 package-installed Qt Creator 并安装带有新 Qt Creator 选项的更新的 Qt 完整框架来解决问题。您可能希望在下载后启用执行文件属性：
chmod +x ~/Downloads/qt-unified-linux-x64-3.2.3-online.run
~/Downloads/qt-unified-linux-x64-3.2.3-online.run
P.S。请注意，上面为用户安装了 Qt Creator 和框架，但当然使用 sudo 并指向正确的位置，我们可以以某种方式为整个系统安装 Qt，但不鼓励这样做：https://forum.qt.io/topic/31366/install-qt-qt-creator-as-root 那么为什么sudo apt install qtcreator 仍然是广泛传播的选择吗？如果是这样，允许其他用户通过一些 soft-link 练习访问您的文件就可以了。
