PHP artisan "PHP Fatal error" on allowed memory size in Laravel

Question

It's confusing, why this error shown. I'm using Laravel 5.4, after using composer update then this error shown.

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
> Illuminate\Foundation\ComposerScripts::postUpdate
> php artisan optimize
PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 495616 bytes) in E:\xampp\htdocs\botble\vendor\symfony\debug\ExceptionHandler.php on line 238
PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 4096 bytes) in E:\xampp\htdocs\botble\vendor\symfony\debug\Exception\FlattenException.php on line 203
Script php artisan optimize handling the post-update-cmd event returned with error code 255

As some of answer on stack and other community, i'm also test this after update php.ini with memory_limit 2048M. But still same error shown.

Any suggestion for this issue.

The error suggests that a 128M memory limit is still in place, I'd investigate as to why your setting isn't applied. — flauntster

have you restarted the server using the command "service apache2 restart" or "service nginx restart" ? — Adarsh Sojitra

I would not globally increase the memory limit, it is there to prevent rogue or buggy scripts from causing a DoS. Instead increase it just for your one use case, ie: php -d memory_limit=2048M /path/to/composer update — Geoffrey

@AdarshSojitra That has nothing to do with it, this is being executed on the CLI which is outside the scope of Apache. And futhermore, Nginx doesn't have a PHP module to reload, it uses a CGI handler (ie, FPM), restarting Nginx has no impact on PHP at all ever. — Geoffrey

@josephting This has nothing to do with the issue, it is clear that the memory_limit is still fixed at 128M after the attempt to raise the limit. — Geoffrey

This is memory limit issue . You can try something like this

Fist find composer directory using bellow command

$>which composer
/usr/local/bin/composer

After you can update composer with memory limit

$>php -d memory_limit=-1 /usr/local/bin/composer update

-1 means unlimited memory
