Qt6.5，大佬帮忙看看是哪里有问题：

QString Widget::getCpuProcessorId()
{
    QString cpuInfo;
#ifdef Q_OS_WIN
    QProcess process;
    process.start("wmic", QStringList() << "cpu" << "get" << "name");
    process.waitForFinished(); // 等待命令执行完毕
    cpuInfo = process.readAllStandardOutput();
#elif defined(Q_OS_LINUX)
    QFile file("/proc/cpuinfo");
    if (file.open(QIODevice::ReadOnly | QIODevice::Text)) {
        while (!file.atEnd()) {
            QString line = file.readLine();
            if (line.startsWith("model name")) {
                cpuInfo = line;
                break;
            }
        }
        file.close();
    }
#endif
    return cpuInfo;
    // return getWMIC("wmic cpu get processorid");
}

我在cmd中实验是有输出的：

程序一直获取不到：
