Centos 7使用:

COMPOSER_MEMORY_LIMIT=-1 composer require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

手册中的另一个解决方案:

Composer也尊重由componer_memory_limit环境变量定义的内存限制:

COMPOSER_MEMORY_LIMIT=-1 composer.phar <...>

或者在我的案例中

export COMPOSER_MEMORY_LIMIT=-1
composer <...>

Here is another way to solve this problem under windows, if you use Wampserver. Indeed at the level of wampserver, there are two php.ini files, that of PHP, which one can find in the location C: \ wamp64 \ bin \ php \ phpx.xx \ php.ini and that of Apache , which can be found at location C: \ wamp64 \ bin \ apache \ apachex.xx \ bin \ php.ini. Both of these files have the memory_limit parameter. So to be sure to solve this problem, it is better to set the memory_limit = -1 parameter in both files at once.

Mac php 7.4

run

php --ini

Configuration File (php.ini) Path: /usr/local/etc/php/7.4
Loaded Configuration File:         /usr/local/etc/php/7.4/php.ini
Scan for additional .ini files in: /usr/local/etc/php/7.4/conf.d
Additional .ini files parsed:      /usr/local/etc/php/7.4/conf.d/ext-opcache.ini,
/usr/local/etc/php/7.4/conf.d/php-memory-limits.ini

如果解析了额外的.ini文件: Memory_limit需要在

/usr/local/etc/php/7.4/conf.d/php-memory-limits.ini

正如Jose Seie所写，设置内存为

memory_limit = -1 or memory_limit = 1G

跳过内存限制和版本错误使用下面的代码:

COMPOSER_MEMORY_LIMIT=-1 composer require <package-name> --ignore-platform-reqs

在我的情况下，当我得到这个错误时，我试图要求这个包。

你可以像这样运行，你不需要更新PHP INI文件:

COMPOSER_MEMORY_LIMIT=-1 composer require huddledigital/zendesk-laravel
