Do not run Composer as root/super user! See https://getcomposer.org/root for details
Warning from https://mirrors.aliyun.com/composer: Support for Composer 1 is deprecated and some packages will not be available. You should upgrade to Composer 2. See https://blog.packagist.com/deprecating-composer-1-support/

解决：

把composer升级到2就行

composer self-update
