我正在尝试在 Qt Creator 中创建一个新的 Qt Quick 应用程序。然而，每次我尝试构建该项目时，甚至在做任何事情之前它都会立即失败。

克隆存储库似乎存在一些问题
https://code.qt.io/qt-labs/qtquickdesigner-components.git这是终端构建输出：

感谢任何有助于解决此问题的帮助或提示。预先感谢！
code.qt.io 今天由于某种未知原因而关闭，但幸运的是，默认的 Qt 应用程序实际上并不那么依赖它。如果您在 CMakeLists.txt 中将 BUILD_QDS_COMPONENTS 选项从 ON 切换为 OFF：
option(BUILD_QDS_COMPONENTS "Build design studio components" OFF)
或者对于旧版本，当它是缓存变量时：
set(BUILD_QDS_COMPONENTS OFF CACHE BOOL "Build design studio components" FORCE)
然后它不会尝试构建和链接 Design Studio 组件，但您的应用程序将在运行时崩溃并出现错误：
module "QtQuick.Studio.Application" is not installed
因为它在 imports//Constants.qml 中依赖于它，但默认情况下似乎未使用此依赖项，因此应用程序在没有它的情况下运行得很好，甚至可以在 Design Studio 中启动。要删除依赖项，只需删除 Constants.qml 中的几行即可：
- import QtQuick.Studio.Application
- property StudioApplication application: StudioApplication {
- fontPath: Qt.resolvedUrl("../../content/" + relativeFontDirectory)
- }
它应该使您的应用程序现在运行得很好，但是当服务器启动时，为了避免将来出现此问题，明智的做法是从 https://code.qt.io/qt-labs/ 克隆依赖存储库qtquickdesigner-components.git 并替换 /qmlcomponents 中的 Fetch_Declare 调用，使其使用本地文件，而不是每次配置项目时从远程获取：
FetchContent_Declare(
ds
SOURCE_DIR "C:/Cloned/Repos/qtquickdesigner-components" # your path to the qtquickdesigner-components repo
)
