关于qt：qt5.7 qmake; “系统找不到指定的路径。” 是什么意思以及如何解决？

Qt5.7 / mingw / windows8.1 qmake。新安装。当我在项目文件上运行qmake时，我收到上述错误消息，尽管发出了makefile，但它们会生成并且项目可以正常工作(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，这些将在哪里。还有qmake要求的任何其他外部状态。

谢谢。

编辑＃1 这是项目文件：

12345678TEMPLATE = app QT += qml quick quickcontrols2 CONFIG += console SOURCES += main.cpp RESOURCES += qml.qrc

编辑2：从QtCreator 4.0.2输出

尝试编辑对PATH变量的更改，一次删除一个目录。在我看来，您正在尝试添加系统上不存在的不必要的路径(由于构建成功，因此没有必要)。

相关讨论谢谢你的建议。遵循这个想法，似乎我安装了mingw的另一个副本(在qt路径之后)，并且qmake搜索sh.exe，它在此其他安装中找到。奇怪的是，当qt安装目录中没有这样的二进制文件时，它将搜索sh.exe。如果我阻止它找到sh.exe，它将生成一个.qmake.stash文件，此后无论路径如何，它都将使用它运行make。但是，此存储文件均未引用其他mingw。如果答案是正确的，您能打上这样吗？谢谢。
