QT中 No such file or directory 问题解决

在运行Qt程序时，有时候其他文件使用某个头文件可以运行，但是到自己这里调用某个头文件时就会报出 No such file or directory 问题。这个一般由于可能安装了多个Qt版本导致qmake调用错误，这个可以再Makefile文件中查看QMAKE变量确认程序使用的是哪个qmake。如果qmake版本没问题就要在Makefile文件中查看INCPATH       = -I../Qt5

这个错误都是由于找不到目标导致的，如果调用的头文件是qt本身自带的，那么先看看qt的pro工程文件中是否将该模块加入进去，然后清除项目重新构建。，这种方式需要QT在安装时包含了相应的模块，如果未包含该模块需要自己去网络下载对应的文件并放到项目中（Qt中拥有大量第三方库，如果要使用这些库必须自己下载后放到项目中）。1.先删掉项目相关的build文件，项目在qmake后重新构建编译，这是由于旧的build文件在项目编译时可能造成影响。2.确定pro工程文件中是否添加相应的模块，如果未添加，在。
