OSX Sierra - 如何正确增加PHP内存限制？

我需要在命令行上增加PHP的内存限制,以便我可以使用Composer.

输出 php -i | grep memory_limit

memory_limit => 256M => 256M

输出 php --ini

Configuration File (php.ini) Path: /usr/local/php5/lib

/usr/local/php5/php.d/60-extension-pecl_http.ini,
/usr/local/php5/php.d/99-liip-developer.ini

所以我编辑/usr/local/php5/lib/php.ini但它总是256MB ......

重启Apache,但它是cli,但仍然没有成功.

其中一个包含的文件有一个memory_limit指令.使用此命令查找哪一个:

grep memory_limit /usr/local/php5/php.d/*

解析"附加的.ini文件"将在稍后解析,并将覆盖主要的设置php.ini.

也许您应该找出php.ini在哪里

有时这不会做：

php -i | grep php.ini   # turns out I just can't edit /etc/php.ini even when I'm root

那么您可以尝试以下操作：

locate php.ini  # turns out it's here: /private/etc/php.ini

最后，使用sudo编辑/private/etc/php.ini

sudo vim /private/etc/php.ini 

用保存文件

:wq!

任务完成。
