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.

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;)

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

我使用命令COMPOSER_MEMORY_LIMIT=-1解决了这个问题

示例:COMPOSER_MEMORY_LIMIT=-1 composer requires larval/ui

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

在你的PHP目录中找到PHP .ini，如果xampp在xampp/PHP中 和内部php.ini文件更新内存限制:512M到2048M
