修复方式

	QStringList portStringLine = {};foreach(const QSerialPortInfo & info, QSerialPortInfo::availablePorts())portStringLine += info.portName();

改为

	QStringList portStringLine = {};QSerialPortInfo* info = new QSerialPortInfo;QList<QSerialPortInfo>* PortAllList = new QList<QSerialPortInfo>;*PortAllList = QSerialPortInfo::availablePorts();foreach(*info, *PortAllList) {portStringLine += info->portName();}delete info;
