Composer update => Fatal error: Out of memory

问题

I'm using XAMPP on a local machine. I couldn't solve this issue by removing the PHP memory limit.

What I already tried :

• modified my php.ini to remove the memory limit => memory_limit=-1

• Checked I was running PHP 5.6

• and self-updated composer to the last version

But it doesn't seem to have any effect at all. Does anyone have a suggestion?

My composer.json:

    }
}

When I run this command:

composer update

I get the following output:

"C:\DEV\xampp\php\php.exe" "C:\DEV\xampp\htdocs\symfony\composer.phar" "--ansi" "--no-interaction" "update"
Loading composer repositories with package information
Updating dependencies (including require-dev)

PHP Fatal error:  Out of memory (allocated 1584922624) (tried to allocate 268435456 bytes) in phar://C:/DEV/xampp/htdocs/symfony/composer.phar/src/Composer/DependencyResolver/Solver.php on line 220

And I expected this to happen:

A simple update as used to happen earlier.

EDIT :

From what I understand, the "Out of memory" error seems to indicate a physical memory limit and not a configured one.

PHP on windows is 32bits (I think so at least...) and 32Bit Processes cannot use more than 2GB of RAM.

So I guess I'm hitting a real physical limitation.

My question now would be : How can I still update my packages on a 32bits PHP ?

I tried updating on a per package approach

C:\DEV\xampp\htdocs\symfony>php -d memory_limit=-1 composer.phar update bmatzner/fontawesome-bundle
Loading composer repositories with package information
Updating dependencies (including require-dev)
PHP Fatal error:  Out of memory (allocated 1592000512) (tried to allocate 268435456 bytes) in phar://C:/DEV/xampp/htdocs/symfony/composer.phar/src/Composer/DependencyResolver/Solver.php on line 220

but as you can see, I encounter the same problem.

回答1:

Upgrading to PHP7 did the trick.

It seems more efficient when it comes to RAM consumption.

Thanks to everyone who tried to help me here.

回答2:

update composer with larger memory limit

php -dmemory_limit=3G /usr/local/bin/composer update
