i have tried this

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
  memory_limit=512M

As well as tried this

 ; Maximum amount of memory a script may consume (128MB)
 ; http://php.net/memory-limit
  memory_limit=-1

but the error is same at the time of installing any library by composer in php laravel

Check firstly if you are editing the right php.ini file, running phpinfo() via the browser. It will show you php.ini file path you're using.

If editing this file doesn't work, try to set Composer's memory limit via with the command php -d memory_limit=-1 composer.phar.
