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

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;)

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.

实际上，如果你设置内存限制为-1(无限)，它应该工作。 例如:

php -d memory_limit=-1 /usr/local/bin/composer update
/usr/bin/php7.1 -d memory_limit=-1 /usr/local/bin/composer update

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
