如题，安装中文插件时候不能成功，提示Connection string is empty

Warning: Your Magento folder does not have sufficient write permissions.

If you wish to proceed downloading Magento packages online, please set all Magento folders to have writable permission for the web server user (example: apache) or set up FTP Connection on the Magento Connect Manager Settings tab.

在setting里面

        Config file does not exists please save Settings
