Error Sample data

[vinhtrau]

This error has occurred when I install new magento2 with sample data.
I already run composer install/update.

PHP Fatal error: Call to undefined method Magento\Catalog\Model\Resource\Product\Interceptor::getWriteConnection() in /private/var/www/magento2/demo_source/app/code/Magento/SampleData/Module/Catalog/Setup/Product/Gallery.php on line 144
