解决方法：
方法一：检查你运行 composer 的php版本是否是 7.4 版本。用 php 7.2 版本试试！！
方法二：如果是用7.4版本，就按标准的写法：
# 先更新源地址
/www/server/php/74/bin/php composer.phar config repo.packaGISt composer https://mirrors.aliyun.com/composer/
# 标准写法
/www/server/php/74/bin/php composer.phar install
--- or ----
/www/server/php/74/bin/php -d disable_functions='' composer.phar require php-di/php-di -W
