untiled2main .cpp:没有这样的文件或目录

Question

我已经在windows上安装了QT5.0.1 with mingw32。当我创建一个项目并运行它时，一切都很完美。下次当我打开QT Qreator并想要运行我的程序时，它有以下错误:

:-1: error: error: ..untitled2main.cpp: No such file or directory

从构建菜单我点击了qmake，它没有错误。这是。pro文件

QT       += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = untitled1
TEMPLATE = app

SOURCES += main.cpp
        mainwindow.cpp 
    contentcontrol.cpp
HEADERS  += mainwindow.h 
    contentcontrol.h
FORMS    += mainwindow.ui 
    contentcontrol.ui

这是编译输出:

是什么问题?

Answer 1

为以后的视图:我通过向环境变量

添加值来解决这个问题

path:
C:QtQt5.0.15.0.1mingw47_32bin;C:QtQt5.0.1ToolsMinGWbin
QTDIR:
C:QtQt5.0.15.0.1mingw47_32

我有同样的问题。修复了项目/建筑环境/清除系统环境中设置为true的复选框。
