add 'QMAKE_MAC_SDK = macosx10.14' to your .pro file, and manually delete .qmake.stash from your build directory (or directories).

将 'QMAKE_MAC_SDK = macosx10.14' 添加到您的 .pro 文件，并从您的构建目录（或多个目录）中手动删除 .qmake.stash。

In my case I updated xcode to the last version, so instead of have on the folder the version 10.13, I had MacOSX10.14.sdk ( that is a symbolic link to the folder MacOSX.sdk)

就我而言，我将 xcode 更新到了最新版本，因此我在文件夹中没有使用 10.13 版本，而是使用 MacOSX10.14.sdk（这是 MacOSX.sdk 文件夹的符号链接）

so, you can solve the problem with this code on terminal:

因此，您可以在终端上使用此代码解决问题：

sudo ln -s MacOSX.sdk/ MacOSX10.13.sdk

positioned on the current folder.

位于当前文件夹中。

I hope it helps.

This helped me:

这帮助了我：

1. Close the project in Qt Creator.
2. Delete the .pro.userfile in your codedirectory.
3. Add QMAKE_MAC_SDK = macosx10.14and QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.14to your .pro file in a text editor (not in Qt Creator). Replace 10.14with whatever MacOS version you want to build for.
4. Re-open the project in Qt Creator. It will reconfigure.
5. Build.

1. 在 Qt Creator 中关闭项目。
2. 删除代码目录中的.pro.user文件。
3. 在文本编辑器（而不是 Qt Creator）中将QMAKE_MAC_SDK = macosx10.14和添加QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.14到您的 .pro 文件。替换10.14为您要为其构建的任何 MacOS 版本。
4. 在 Qt Creator 中重新打开项目。它会重新配置。
5. 建造。
