要获取当前的memory_limit值，运行:

php -r "echo ini_get('memory_limit').PHP_EOL;"

尝试增加php.ini文件中的限制(例如/etc/php5/cli/php.ini对于debian类系统):

; Use -1 for unlimited or define an explicit value like 2G
memory_limit = -1

或者，你可以用命令行参数增加限制:

php -d memory_limit=-1 composer.phar require hwi/oauth-bundle php-http/guzzle6-adapter php-http/httplug-bundle

要加载php.ini文件，请尝试:

php --ini

另一个快速解决方案:

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

或者是:

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

我在这里将有用且被接受的答案压缩或打包成可重用(zsh)别名/函数，以便更快更容易记住重用:

# composer high-memory
composermem() {
  php -r "echo ini_get('memory_limit').PHP_EOL;"
}
alias composerbig='COMPOSER_MEMORY_LIMIT=-1 composer $1'

(php作曲家。Phar已经在系统上别名为composer)。

最近发现，Composer在具有大量历史标记的包上消耗了大量CPU +内存。看到作曲家/作曲家# 7577

这个问题的解决方法是使用symfony/flex或https://github.com/rubenrua/symfony-clean-tags-composer-plugin

composer global require rubenrua/symfony-clean-tags-composer-plugin

以防你得到一个作曲家错误:

无法打开输入文件:composer

run:

php -d memory_limit=-1 /usr/local/bin/composer require ...

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
