Xampp使用composer命令退出内存

Question

安装最新版本的xampp 8.0.9后，当我从xampp面板打开终端时，我有另一个操作系统作为Debian，

uname -a -r
Linux debian 4.19.0-17-amd64 #1 SMP Debian 4.19.194-3 (2021-07-18) x86_64 GNU/Linux

现在导航到htdocs文件夹内的php项目后，我尝试使用composer upadte来安装和更新composer.json包，但我得到这个错误:

composer update
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Loading composer repositories with package information
Warning from https://repo.packagist.org: Support for Composer 1 is deprecated and some packages will not be available. You should upgrade to Composer 2. See https://blog.packagist.com/deprecating-composer-1-support/

mmap() failed: [12] Cannot allocate memory
PHP Fatal error:  Out of memory (allocated 798220288) (tried to allocate 32134463 bytes) in /usr/share/php/Composer/Util/RemoteFilesystem.php on line 459
Fatal error: Out of memory (allocated 798220288) (tried to allocate 32134463 bytes) in /usr/share/php/Composer/Util/RemoteFilesystem.php on line 459

当我得到这个错误时，我尝试将memory_limit更改为php.ini文件，然后我运行这个命令:

php --ini

输出:

Configuration File (php.ini) Path: /opt/lampp/etc
Loaded Configuration File:         /opt/lampp/etc/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

这里memory_limit是-1，因为我安装了php 8.0.9，它没有php文件夹在/etc/，我只有php 7.3

php -v

输出:

PHP 8.0.9 (cli) (built: Jul 30 2021 09:12:42) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.9, Copyright (c) Zend Technologies

在php 7.3文件夹中打开php.ini来更改memory_limit，此选项值也有-1

现在我如何增加memory_limit和解决这个问题?

最后运行这个命令没有给我任何输出或结果:

php -d memory_limit=1024M /usr/bin/composer update

Answer 1

try

php -d memory_limit=-1 composer update

，以便独立于ini文件设置限制。

根据php --ini, php 8的php.ini文件位于/opt/lampp/etc/php.ini中，而不是/etc/

Answer 2

每当我尝试在laravel中使用种子器同时上传10万数据时，我都会遇到同样的问题

1. 首先你可以尝试PHP的chunk函数来尝试上传一些数据

foreach (array_chunk($object_array,1000) as $t)  
{
DB::table('table_name')->insert($t); 
}

然后运行php artisan o:c

2. 在终端运行命令

free -m

这是释放你的内存
