Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

解决办法1：运行命令时增大内存

php -d memory_limit=3G /usr/local/bin/composer update

解决办法2：不限制内存大小

php -d memory_limit=-1 /usr/local/bin/composer update

解决办法3：把php.ini的memery_limit增大

memery_limit=4096M
