The error message “module ‘QtQuick.Controls’ is not installed” suggests that the Qt Quick Controls module is not properly installed or accessible in your development environment.
To resolve this issue, you can try the following steps:
Make sure that you have Qt Quick Controls installed as part of your Qt installation. You can check this by opening the Maintenance Tool (usually found in the Qt installation folder) and verifying that the corresponding module is selected for installation.
Ensure that the correct version of Qt Quick Controls is being used in your project configuration. Check your project’s .pro or .qmlproject file to confirm that you have specified the correct version of Qt Quick Controls as a dependency.
If you are using an IDE like Qt Creator, try cleaning and rebuilding your project to ensure all dependencies are resolved correctly.
