It's ok last few days, but today I got this problem and it can' generate the qrcode image for me, and before this I din't change anything, actually there is no file named rsc0.dat in the path, below is my code :

$qrCode = new QrCode();
        $qrCode
            ->setText($string)
            ->setSize(300)
            ->setPadding(10)
            ->setErrorCorrection('high')
            ->setForegroundColor(array('r' => 0, 'g' => 0, 'b' => 0, 'a' => 0))
            ->setBackgroundColor(array('r' => 255, 'g' => 255, 'b' => 255, 'a' => 0))
            //->setLabel($label)
            //->setLabelFontSize(16)
            ->setImageType(QrCode::IMAGE_TYPE_PNG)
        ;
        return $qrCode;

what's wrong with me ?

parameters:

$string = 'I864';
$label = '';
