Qt5.7/mingw/windows8.1 qmake。全新安装。当我在项目文件上运行 qmake 时，我收到上述错误消息，虽然发出了 makefile，但它们构建并且项目工作（看起来）。
从命令行运行 qmake；这是我添加到 PATH 的路径：
I:\Qtmg\Qt5.7.0\5.7\mingw53_32\bin;i:\Qtmg\Qt5.7.0\Tools\mingw530_32\bin;I:\Qtmg\Qt5.7.0\Tools\QtCreator\bin
这与配置文件或缓存有关吗？如果是这样，这些会在哪里。还有 qmake 需要的任何其他外部状态。
谢谢。
EDIT#1 这里是项目文件：
TEMPLATE = app
QT += qml quick quickcontrols2
CONFIG += console
SOURCES += main.cpp
RESOURCES += qml.qrc
编辑#2：QtCreator 4.0.2 的输出
