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;)

在我的例子中，我丢失了一个交换分区。更多信息:https://github.com/composer/composer/issues/7348#issuecomment-414178276

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.

你只需要增加“php.ini”文件的内存限制来解决这个问题

在php.ini文件中找到“memory_limit”。

只需将memory_limit值更改为2G，如下所示

;http://php.net/memory-limit
memory_limit=2G

使用以下命令重新定位PHP文件。

php --ini

在Windows xampp我只是改变:

;memory_limit=512M 

在php.ini中:

memory_limit =-1

然后通过xampp重新启动Apache

结果如下:

; Maximum amount of memory a script may consume
; http://php.net/memory-limit
memory_limit =-1
;memory_limit=512M

Centos 7使用:

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