C++ 项目 QML QtQuick.Controls“ is not installed

c++ 项目中引入qml文件，只导入 import QtQuick 时，能够正常展示

import QtQuick

然而，导入其他模块，如 QtQuick.Controls 、 QtQuick.Layouts等，运行时，会报错：

"module "QtQuick.Layouts" is not installed"

"module "QtQuick.Controls" is not installed"

"module "QtQuick.Layouts" is not installed"

等错误。

解决：

增加环境变量：

QML2_IMPORT_PATH： C:\Qt\6.8\6.8.3\msvc2022_64\qml
