我完全不知所措，希望有人能提供帮助。我已经习惯了Visual Studio环境和设置，而QT对我来说却是新的。我正在运行Linux Mint（debian 20.04），并安装了qt5-default和qtcreator。 QT创建者第一次加载良好，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。我一直在努力地研究Google和Stack，发现了一些类似的问题，但是到目前为止，没有找到适合我的解决方案。尝试从终端运行qtcreator会显示以下输出：

从输出中看，似乎有两个相互矛盾的版本，但是，作为QT的新手，我不确定如何或将其指向正确的版本。感谢您的帮助！

我们应该有很多行，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user的根目录而不指向/home/user表示我们已经安装了sudo apt install qtcreator的Qt Creator（不是真正的最新Qt框架，甚至不是Creator），这可能可以作为较旧的IDE派上用场，但没有太多其他优点，并且由于许多库软链接重定向等原因而容易出现系统错误。
首先将其清除出系统：
sudo apt purge qtcreator
按照原始发布者的要求，通过使用Qt Maintenance Tool，完全删除了软件包安装的Qt Creator并安装了带有新Qt Creator选件的新Qt完整框架，从而解决了问题。在下载执行文件属性后，您可能要为其启用该功能：
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，以上内容为用户安装了Qt Creator和框架，但当然要使用sudo并指向正确的位置，我们可以以root用户身份为整个系统安装Qt，但不建议这样做：https://forum.qt.io/topic/31366/install-qt-qt-creator-as-root那么为什么呢？ 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软链接练习访问您的文件。
