我尝试在 MAC OS 上使用 QML 构建应用程序。开始构建时出现错误。

Could not parse otool output: "/Users/test/qt/dev/projects/TestProject/build-rproxychecker2-Desktop_Qt_5_15_2_clang_64bit-Debug/debug/ch2.app/Contents/Resources/qml/QtQml/Models.2/libmodelsplugin.dylib.dSYM/Contents/Resources/DWARF/libmodelsplugin.dylib:\n"

我使用 QT 5.15.2、Xcode 10.3、QtCreator 5.0 并且有一个包含这些参数的 .pro 文件。

QT += core gui network sql quickwidgets quick quickcontrols2 
...
lupdate_only {
    SOURCES += qml
}
...
macdeployqt $${DESTDIR}/$${TARGET}.app -qmldir=$${PWD}/qml -always-overwrite;

我尝试在没有 -always-overwrite https://bugreports.qt.io/browse/QTBUG-57265 的情况下调用 macdeployqt，但没有帮助。有人有同样的问题吗？

【解决方案1】：

如果有人有这个问题。您必须删除所有出现此类错误的文件

rm -rf "/Users/test/qt/dev/projects/TestProject/build-rproxychecker2-Desktop_Qt_5_15_2_clang_64bit-Debug/debug/ch2.app/Contents/Resources/qml/QtQml/Models.2/libmodelsplugin.dylib.dSYM" 
rm -rf "/Users/test/qt/dev/projects/TestProject/build-rproxychecker2-Desktop_Qt_5_15_2_clang_64bit-Debug/debug/ch2.app/Contents/Resources/qml/QtQml/Models.2/libmodelsplugin_debug.dylib.dSYM"

最好在 .pro 文件中制作。
