Composer require runs out of memory. PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted

To get the current memory_limit value, run:

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

Try increasing the limit in your php.ini file (ex. /etc/php5/cli/php.ini for Debian-like systems):

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

Or, you can increase the limit with a command-line argument:

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

To get loaded php.ini files location try:

php --ini

Another quick solution:

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

Or just:

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

---

In my case I was trying to require this package when I got this error.

You can run like this, and you don't have to update the PHP INI file:

COMPOSER_MEMORY_LIMIT=-1 composer require huddledigital/zendesk-laravel

---

Another solution from the manual:

Composer also respects a memory limit defined by the COMPOSER_MEMORY_LIMIT environment variable:

COMPOSER_MEMORY_LIMIT=-1 composer.phar <...>

Or in my case

export COMPOSER_MEMORY_LIMIT=-1
composer <...>

---

Same problem, none of anything related to "memory_limit" worked, but..

composer self-update --2

..solved my problem. (upgrade: 1.10.17 -> 2.0.4)

---

On Windows 10;

Goto C:\ProgramData\ComposerSetup\bin

Edit: composer.bat and add memory_limit=-1 in the last line as shown below.

@echo OFF
:: in case DelayedExpansion is on and a path contains ! 
setlocal DISABLEDELAYEDEXPANSION
php -d memory_limit=-1 "%~dp0composer.phar" %*

Problem solved ;)

Since none of the previous answers included set it took me a bit to figure out how to do it in Windows without altering the php.ini, but here's what worked for me:

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

---

I have bypassed the problem in a Homestead Laravel (vagrant) virtual machine running the composer commands preceded by COMPOSER_MEMORY_LIMIT=-1:

Examples

To update Composer:

COMPOSER_MEMORY_LIMIT=-1 composer update

To install a package:

COMPOSER_MEMORY_LIMIT=-1 composer require spatie/laravel-translatable

---

For this error in macOS Catalina and macOS Big Sur use this line:

php -d memory_limit=-1 /usr/local/bin/composer update --no-plugins

I used this line to update on Symfony 5. This command also worked with laravel 7.

---

Just set the memory_limit specifying the full route of your composer.phar file and update, in my case with the command:

php -d memory_limit=-1 C:/wamp64/composer.phar update

---

Sometimes the problem is in the composer memory limit. In my case, I tried increasing the php memory limit but still got the error. You can use COMPOSER_MEMORY_LIMIT=-1 to get around that. Use it as a prefix:

COMPOSER_MEMORY_LIMIT=-1 composer require the/library

You have to prefix it again in the future.

Hope this helps.

It was recently identified that Composer consumes high CPU + memory on packages that have a lot of historical tags. See composer/composer#7577

A workaround to this problem is using symfony/flex or https://github.com/rubenrua/symfony-clean-tags-composer-plugin

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

---

Just in case you get a composer error with:

Could not open input file: composer

run:

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

---

For skipping memory limit and version error use the code below:

COMPOSER_MEMORY_LIMIT=-1 composer require <package-name> --ignore-platform-reqs

---

what about windows?

i use windows 10 and this command worked for me,

php -d memory_limit=-1 "C:\ProgramData\ComposerSetup\bin\composer.phar" update

---

Composer 2.0 preview is available now: https://github.com/composer/composer/releases Fixed issue for me. You can set up a preview with composer self-update --preview

EDIT: Composer 2 with memory tuning released

---

You can use a specific php Version when running Composer

If, like me, for some reason, you are using PHP 32 bits even though your computer is 64 bits, this will always limit the amount of memory allocated to Composer. I solved my problem this way:

Install a 64 bits php version somewhere on your computer (let's say in C:/php64)

In composer (using cygwin in my case), run:

COMPOSER_MEMORY_LIMIT=-1 C:/php64/php.exe ../composer.phar update

---

in windows by xampp i just changed:

;memory_limit=512M 

in php.ini to:

memory_limit =-1

then restart the Apache by xampp

this is the result:

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

On 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

If Additional .ini files parsed: memory_limit needs to be changed in

/usr/local/etc/php/7.4/conf.d/php-memory-limits.ini

As Jose Seie writes, set memory to

memory_limit = -1 or memory_limit = 1G

Just want to share my situation on this matter.

Problem context:

Running composer in a vagrant box. Was getting this message after try to run composer require "laravel-doctrine/orm:~1.4.13":

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52 Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

Have tried setting php.ini memory limit to -1. (still not working).

Solution:

Apparently my composer.json and composer.lock has some issues. Ran $ composer validate, and the result was: "The lock file is not up to date with the latest changes in composer.json, it is recommended that you run composer update." So I ran $ composer update, and all dependencies are resolved. Imho, when the dependencies has some issues, maybe the tree building is out of sync, hence the out of memory issue.

Hope this helps anyone out there.

To override this and fix the issue on your local machine you can do the following changes within your php.ini configuration file.

To locate your php.ini configuration file you can use the following command: php --ini

After running this command you should see an output like the following:

Configuration File (php.ini) Path: /usr/local/etc/php/7.3
Loaded Configuration File:         /usr/local/etc/php/7.3/php.ini <---- note the path
Scan for additional .ini files in: /usr/local/etc/php/7.3/conf.d
Additional .ini files parsed:      /usr/local/etc/php/7.3/conf.d/ext-opcache.ini

The file we want to change is the Loaded Configuration.

Open and search for the memory_limit you can set the memory_limit = -1 to give an unlimited amount of memory to PHP processes or you can set 512MB, 1G, 2G, 5G,.... $ nano /usr/local/etc/php/7.3/php.ini

locate and set:

$ memory_limit = -1 or memory_limit = 1G

After saving your file, you can verify the PHP changes by running this command which will output the current memory settings in your php.ini file: php -r "echo ini_get('memory_limit').PHP_EOL;"

NOTE: After saving, the new memory will be working. You don't need to do anything else.

for Centos 7 use :

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

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/RuleWatchGraph.php on line 52 Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.

set memory_limit to -1 works for me ;) (vim /etc/php/7.2/cli/php.ini)

---

For Macbook: run command sudo nano ~/.bash_profile to edit bash_profile then add alias composer="COMPOSER_MEMORY_LIMIT=-1 composer" in that file, then save and exit.

Hope this will solve the problem; Happy coding!

---

I condensed or packaged up the useful and accepted answer here into reusable (zsh) aliases/functions, for quicker and easier-to-remember reuse:

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

(php composer.phar is already aliased to composer on the system).

---

I solved this problem using this command COMPOSER_MEMORY_LIMIT=-1

Example: COMPOSER_MEMORY_LIMIT=-1 composer requires larval/ui

---

For me, this works on shared hosting.

COMPOSER_MEMORY_LIMIT=-1 composer update

---

In My case i've tried to install the Laravel framework without stating xampp server (or apache server) in my windows system and i got following error

Fatal error: Allowed memory size of 1610612736 bytes exhausted

as soon as i started the xampp server (or apache server) it started to install the laravel framework and error gone away.

So actually sometimes you have to check this or else it will take longer time than usual and consume more memeory and in result size will be exhausted.

---

Make sure to not require a package before making sure the vendor folder exists.

Check if you have done composer install before. You may be just cloned the repository to your machine. So, you have to install the old packages before requiring a new one. Or you may want to include this option --profile to your composer command to see the timing and memory usage information.

---

In my case:

Windows 10 and Docker Desktop works:

docker-compose -f .docker/docker-compose.yml exec php env COMPOSER_MEMORY_LIMIT=-1 composer require fideloper/proxy

---

You just need to increase memory limit on "php.ini" file to solve the problem

find the "memory_limit" in php.ini file.

just change memory_limit value to 2G like below

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

to relocate the php file by using below command.

php --ini
