更精确地说，解决方案一:

COMPOSER_MEMORY_LIMIT=-1作曲家更新

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.

在我的例子中:

Windows 10和Docker Desktop工作:

docker-compose -f .docker/docker-compose.yml exec php env COMPOSER_MEMORY_LIMIT=-1 composer require fideloper/proxy

Windows 10;

后藤C: \ ProgramData ComposerSetup \ bin

编辑:composer.bat并在最后一行添加memory_limit=-1，如下所示。

@echo OFF
:: in case DelayedExpansion is on and a path contains ! 
setlocal DISABLEDELAYEDEXPANSION
php -d memory_limit=-1 "%~dp0composer.phar" %*

问题解决了;)

对我来说，这适用于共享托管。

COMPOSER_MEMORY_LIMIT=-1 composer update

Centos 7使用:

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