I'm working in developer mode, with all caches off. This started occuring after upgrading from 2.0.X to 2.1.0rc2

It seems like Symfony isn't working properly...

Answer 1

This may not be the best answer, but i've found that updating the remote server, then synchronizing the files to my local machine cleared up any issues.

Answer 2

• Check if \Magento\Framework\Console\CommandListInterface exists as it is called in lib/internal/Magento/Framework/Console/Cli.php:140
• Check \Magento\SampleData\Console\CommandList as it extends Magento\Framework\Console\CommandListInterface that may not exist.
• Check app/etc/di.xml if it has correct preference for Magento\Framework\Console\CommandListInterface.
• Clean cache.

Answer 3

Can happen due to permissions, try:

chmod 777 -R .

(Or more secure equivalent) in the application directory and re-run your command.
