QT安装No login url found

这个错误通常是由于Qt安装程序无法连接到Qt的登陆服务器导致的。解决方法如下：

1. 检查系统网络设置，确保你的计算机能够正常访问Internet。

2. 如果你使用的是代理服务器，请确保Qt安装程序已配置为使用正确的代理设置。

3. 尝试使用Qt离线安装程序进行安装。离线安装程序不需要连接到Qt的服务器。

4. 如果以上方法都没有解决问题，请尝试手动下载Qt安装程序并进行安装。你可以在Qt官网上找到所有版本的Qt安装程序。

希望这些方法能够帮助你解决问题。

QT:no suitable kits found.

这个问题通常是因为Qt Creator没有找到可用的编译套件。你可以尝试以下几个步骤来解决：

1. 确保你已经安装了Qt编译器和Qt Creator，并且它们都已经正确配置。

2. 在Qt Creator中选择“工具”>“选项”>“Kits”，检查是否已经添加了可用的编译套件。如果没有，请点击“添加”，选择你的编译器和Qt版本，并按照提示进行配置。

3. 如果你已经添加了套件但仍然无法使用，请尝试在Qt Creator中选择“工具”>“选项”>“构建和运行”，检查你的默认构建套件是否正确，并尝试手动切换到另一个可用的套件。

4. 最后，你可以尝试重新安装Qt Creator和Qt编译器，并确保它们都是最新版本，并重新配置它们以确保正确性。
