How to Resolve Composer Update Memory Limit Errors on Remote Servers?

Resolving Composer Update Memory Limit Error

Problem:

When attempting to run composer update on a remote server via SSH, users may encounter a memory limit error.

Error Message:

Fatal error: Allowed memory size of 134217728 bytes exhausted

Solution:

1. Increase the Memory Limit Using a Command:

As suggested by the hosting provider, try running the command with an increased memory limit:

php -d memory_limit=512M composer update

2. Set the COMPOSER_MEMORY_LIMIT Variable:

If the above command fails, the issue may be with the composer executable file. Set the COMPOSER_MEMORY_LIMIT environment variable to remove any memory limit restrictions:

COMPOSER_MEMORY_LIMIT=-1 composer update

This allows Composer to allocate unlimited memory during the update process.
