Macdeployqt 找不到要部署的任何外部 Qt 框架

Question

我在Qt/Qml中制作了一个简单的动画。我可以很好地构建发布版本，没有错误。它也能正常运行。项目完成后，我尝试像这样用 macdeployqt 部署它：

./Qt/5.6/clang_64/bin/macdeployqt /Users/etcg/Documents/qt/build-Windmill-Animation-Executer-Desktop_Qt_5_6_0_clang_64bit-Release/Windmill-Animation-Executer.app

但它给了我以下错误：

WARNING:
WARNING: Could not find any external Qt frameworks to deploy in "/Users/etcg/Documents/qt/build-Windmill-Animation-Executer-Desktop_Qt_5_6_0_clang_64bit-Release/Windmill-Animation-Executer.app"
WARNING: Perhaps macdeployqt was already used on "/Users/etcg/Documents/qt/build-Windmill-Animation-Executer-Desktop_Qt_5_6_0_clang_64bit-Release/Windmill-Animation-Executer.app" ?
WARNING: If so, you will need to rebuild "/Users/etcg/Documents/qt/build-Windmill-Animation-Executer-Desktop_Qt_5_6_0_clang_64bit-Release/Windmill-Animation-Executer.app" before trying again.

是我做错了什么，还是我的Qt安装有问题？我该如何解决这个问题？

注意：这是我第一次使用macdeployqt。

编辑：

为了检查依赖库，我运行 otool -L.

otool -L /Users/etcg/Documents/qt/build-Windmill-Animation-Executer-Desktop_Qt_5_6_0_clang_64bit-Release/Windmill-Animation-Executer.app/Contents/MacOS/Windmill-Animation-Executer的结果是这样的：

跟着我们在chat, it seems that you managed to get it working, so that's great! As I suspected, your @rpath was misleading (Qt's fault I guess). So the way to fix it is to link the Qt libraries using @executable_path instead of @rpath (you can go here中的讨论就知道区别了）。

为此，请按照下列步骤操作：

1/ 运行可执行文件本身：您将收到如下错误消息：

dyld: Library not loaded: @rpath/Qt*.framework/Versions/5/Qt*

Referenced from: your_executable_name

Reason: image not found Trace/BPT trap: 5

其中 * 是 Qt 库的名称。您被告知该库未被很好地引用，因此 您必须更改引用它的路径 。

2/ 要做到这一点，使用命令 install_name_tool 像这样：

install_name_tool -change @rpath/Qt*.framework/Versions/5/Qt* @executable_path/your/path/to/the/framework/Qt*.framework/Versions/5/Qt* /your/path/to/your/executable

现在，您已经更改了路径（您可以使用 otool -L 检查）。

3/ 如果更改正确，要么你没有问题了，要么你必须为其他 Qt 库执行此操作。实际上，* 可以是 Quick，但也可以是 Gui、Network 等（实际上是 Qt 库）。所以回到第 1 步！

完成所有库后，您的应用程序将按照您的需要启动。
