[guoguolong]

It's redirected to http://<magento2_host>/downloader/?return=http%3A%2F%2Fmagento2.me%2Findex.php%2Fbackend%2Fadmin%2F when I enter Connect Manager from backend.

The page is blank. I found below errors in php log files.

PHP Fatal error: Class 'Magento\Autoload\Simple' not found in /projects/magento2/downloader/index.php on line 33

Hello guoguolong,
Thank you for reporting this issue! You experienced the mentioned error because we are redesigning Magento Connect Manager for Magento 2. The version of MCM used in Magento 1 will not be used in the new version of Magento. Please wait till we release the new version of Connect Manager.
