c++ - QTcpServer错误C1083， "no such file or directory"

Question

我正在使用 Qt 5.4.1 离线版本，我收到了 QTcpServer 的文件未找到错误。我发布了我的 .pro 文件以表明我确实有 += 网络。如果您知道我为什么会收到此错误，请告诉我!谢谢!

QT       += core
QT       += network
QT       -= gui

TARGET = MultiServer2
CONFIG   += console
CONFIG   -= app_bundle

TEMPLATE = app


SOURCES += main.cpp \
    myserver.cpp \
    mythread.cpp

HEADERS += \
    myserver.h \
    mythread.h

//下面开始服务器头文件

#ifndef MYSERVER_H
#define MYSERVER_H

#include <QTcpServer>     //  <--- THIS IS WHAT IS NOT BEING FOUND
#include <QDebug>
#include "mythread.h"

class MyServer : public QTcpServer
{
    Q_OBJECT
public:
    explicit MyServer(QObject *parent = 0);
    ~MyServer();

    void startServer();

signals:

public slots:

protected:
    void incomingConnection(int socketDescriptor);

};

#endif // MYSERVER_H

如果 .pro 文件有任何变化(如果添加 Qt += 网络)，您需要重新运行 qmake

Build->Run qmake.
