QT Creator出錯

Question

你好我正在用QT Creator發生編譯錯誤，我想知道是否有人知道爲什麼會出現這些錯誤。由於

main.cpp中：

#include <QApplication> 
#include <QGraphicsScene> 
#include <QGraphicsRectItem> 
#include <QGraphicsView> 


int main(int argc, char *argv[]){ 

    QApplication a(argc, argv); 

    //Create Scene 
    QGraphicsScene * scene = new QGraphicsScene(); 

    //Creat Item To Put Into Scene 
    QGraphicsRectItem * rect = new QGraphicsRectItem(); 
    rect->setRect(100, 50, 100, 100); 

    //Add Item To Scene aka buffer 
    scene->addItem(rect); 

    //add a view 
    QGraphicsView * view = new QGraphicsView(scene); 
    view->show(); 

    return a.exec(); 
} 

mygame.pro：

編譯輸出：

Error while building/deploying project mygame (kit: Desktop Qt 5.8.0 MSVC2015_64bit) 
When executing step "qmake" 

我沒有確定是什麼讓這些錯誤（單詞和更多的單詞更詳細，所以「看起來你的文章需要更多的細節」將消失...它不會消失，所以我會繼續打字，直到它選擇這樣做，但看起來它不會很快。我們去了）。

Answer 1

看看編譯輸出選項卡。如果需要，還可以在命令提示符下運行qmake。

修復奇怪的qmake錯誤的另一個有用的方法是在Qt Creator中獲得新的項目設置。

關閉Qt Creator，刪除.pro.user文件，然後用您的項目重新打開Qt Creator。這將迫使你用你的Qt版本調試/發佈等來重新配置你的項目。

希望有所幫助。
