亲测可用！！ QT数据库驱动插件必须放在特殊的子目录下（如plugins/xxx） QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL"); db.setHostName("acidalia"); db.setDatabaseName("customdb"); db.setUserName("mojito"); db.setPassword("J0a1m8"); db.open();

分别将文件夹中的bin文件夹中的dll，和lib文件夹中的文件 对应复制覆盖到：Qt安装目录下（以默认路径为例），解决Qt5.13.1中QSerialPort 模块中 ReadyRead信号不触发的问题。 C:\Qt\Qt5.13.1\5.13.1\mingw73_64 --->bin \ lib 中 C:\Qt\Qt5.13.1\5.13.1\msvc2017_64 --->bin \lib 中
