ink [Composer\Downloader\TransportException] The "https://extiverse.com/satis/packages.json" file could not be downloaded (HTTP/1.1 404 Not Found) 我查了很久，网上的方法并不奏效！希望大家帮帮我，谢谢
yannis ink chenran 将下载源换成默认的试试看，可能是换成国内源造成的， composer config -g repo.packagist composer https://packagist.phpcomposer.com 如果之前切换到了国内源，也可以取消配置 composer config -g --unset repos.packagist
