If you encounter the error message “QtQuick” version 2.12 is not installed, it means that the required version of QtQuick is missing from your development environment.
To resolve this issue, you can try the following steps:
Make sure you have installed the correct version of Qt and QtQuick on your system. You can download the necessary installer from the official Qt website.
Check your project configuration to ensure that it is set up correctly for the desired version of Qt and QtQuick. Double-check the QML import statements in your code to match the correct version.
If you are using an integrated development environment (IDE) like Qt Creator, verify that the correct kit or compiler is selected for your project, as it may affect which versions of libraries are used.
Clean and rebuild your project to ensure that any previous build artifacts are removed and rebuilt with the updated settings.
If these steps do not resolve the issue, you may need to provide more details about your development environment and specific errors encountered for further assistance.
