尝试运行代码时在空QT项目中链接错误

如何解决尝试运行代码时在空QT项目中链接错误

当我使用QT Creator在开源QT版本的空项目中按“运行”时，发生链接错误： ''' lnk1104无法打开文件'qtmaind.lib' ''' 在安装过程中，我启用了“ MSVC 2017”和“ MinGW 5.3.0”选项，根据google的回答，应该可以解决此问题。

这是我的.pro文件：

QT       += core gui
 
greaterThan(QT_MAJOR_VERSION,4): QT += widgets
 
CONfig += c++11
 
# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to kNow how to port your code away from it.
DEFInes += QT_DEPRECATED_WARNINGS
 
# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so,uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFInes += QT_disABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
