 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

上面就是我的解决方法，被坑了好久才找到的，如果你解决了，评论区留言告诉我！

然后，你就快乐的等待着安装完成吧！！
