Hi!
I've downloaded Magento CE 2,1 using composer (create-project).
After that, I switched to browser and tried to install Magento 2.1. with Wizard. But instead to start installation process I've got Fatal Error.
Fatal error: Uncaught Error: Cannot instantiate interface Magento\Framework\App\Config\Scope\ReaderPoolInterface in /var/www/html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:73 Stack trace: #0 /var/www/html/magento2/vendor/magento/framework/ObjectManager/ObjectManager.php(71): Magento\Framework\ObjectManager\Factory\Dynamic\Developer->create('Magento\\Framewo...') #1 /var/www/html/magento2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(126): Magento\Framework\ObjectManager\ObjectManager->get('Magento\\Framewo...') #2 /var/www/html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php(53): Magento\Framework\ObjectManager\Factory\AbstractFactory->resolveArgument(Array, 'Magento\\Framewo...', NULL, 'readerPool', 'Magento\\Framewo...') #3 /var/www/html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php(82): Magento\Framework\ObjectManager\Factory\Dynamic\Developer->_resolveArguments('Magento\\Framewo...', Array, Array) #4 in /var/www/html/magento2/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 73
What's wrong?
Same problem here.
I have installed a fresh Magento 2.1 in the public_html folder and it works, but I tried to have a second install for testing purposes in public_html/test. Uploaded the same package to public_html/test, extracted it and when I want to go to the web interface and start the install process, I get this:
Fatal error: Cannot instantiate interface Magento\Framework\App\Config\Scope\ReaderPoolInterface in /home/[mydomain]/public_html/test/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php on line 73
try to use CLI magento installation way
Got the same issue. Fixed by tweaking virtual host configuration. You can find the details here.
