我正在使用Yarn处理软件包。

yarn install不管我使用哪个软件包，都会显示错误，但安装看起来已成功完成，并且文件node-modules直接位于下面。（jquery-ui不出现在下方node-modules）

我删除yarn.lock并再次尝试，但徒劳无功。

有人可以帮忙吗？

我的环境如下所示：

whitebear$ yarn -v
1.10.1
whitebear$ node -v
v11.0.0
whitebear$ npm -v
6.4.1

我正在制作可以合成相机预览和png的相机应用程序.

我想将图像保存在onPictureTaken回调中

我的来源如下

    public void onPictureTaken(byte[] data, Camera camera) {

            //preview from camera
            Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length); 

            // overlay image 
            Bitmap overlayBmp = overlay.getDrawingCache(); 

            //blank beatmap 
            Bitmap blankBitmap = 
            Bitmap.createBitmap(bitmap.getWidth(),bitmap.getHeight(), 
            Bitmap.Config.ARGB_8888); 

            //make canvas
            Canvas canvas = new Canvas(blankBitmap); 

            //composite image
            canvas.drawBitmap(bitmap, null,new Rect(0, 0, bitmap.getWidth(), 
    bitmap.getHeight()), null); 
            canvas.drawBitmap(overlayBmp, null,new Rect(0, 0, bitmap.getWidth(), 
    bitmap.getHeight()), null); 

然而,它显示了outofmemoryerrorror,我怎么能解决这个问题..？

我正在使用symfony2和FOSUserBundle.

通常,我可以从Controller获取用户数据

$user = $this->get('security.context')->getToken()->getUser();

要么

$user = $this->container->get('security.context')->getToken()->getUser(); 

但是现在,我想从eventlistner获取从Ajax调用的userdata.

可能吗？或不？

我的来源在这里.

    namespace Acme\MemberBundle\EventListener;

    use ADesigns\CalendarBundle\Event\CalendarEvent;
    use ADesigns\CalendarBundle\Entity\EventEntity;
    use Doctrine\ORM\EntityManager;

    class CalendarEventListener
    {
        private $entityManager;

        public function __construct(EntityManager $entityManager)
        {
            $this->entityManager = $entityManager;
        }

        public function loadEvents(CalendarEvent $calendarEvent)
        {
            $startDate = $calendarEvent->getStartDatetime();
            $endDate = $calendarEvent->getEndDatetime();


           $user = $this->container->get('security.context')->getToken()->getUser();//it doesnt work

            // load events using your custom logic here,
            // for instance, retrieving events from a repository

            $companyEvents = $this->entityManager->getRepository('UserBundle:MutorSche')
                    ->createQueryBuilder('company_events')
                    ->where('company_events.event_datetime BETWEEN :startDate and :endDate')
                    ->setParameter('startDate', $startDate->format('Y-m-d H:i:s'))

你怎么逃避教义？

我做了这个代码

$query = $em->createQuery(
                "SELECT a FROM AcmeTopBundle:ArtData a WHERE
                a.name = '". mysql_escape_string($name) ."'");

但当$ name是A'z时

它返回错误

[Doctrine\ORM\Query\QueryException]          
SELECT a FROM AcmeTopBundle:ArtData a WHERE  
                a.name = 'A\'s'  

我想我mysql_escape_string在使用原始sql的情况下逃脱了.

如何避免学说上的这个错误？
