Solved: Error in Compat.php While Installing Magento 2

Hello Magento Peeps,

Stumbled upon an unexpected error in compact.php while installing Magento 2? 🤔

We’ve got you covered, probably! 😃😇😊

Recently, I installed Magento 2 with XAMPP on a Windows PC of one of my colleagues and encountered an unexpected error. The error read:

In compat.php line 1927:

This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP.

On further investigation, I found that the error was thrown by Magento because certain PHP extensions were missing.

Method to Solve Error in Compat.php During Magento 2 Installation

Magento 2 is a PHP-based eCommerce platform and requires certain resources to function properly. You can check out Magento 2 system requirements for your reference.

Coming back to the issue, the “This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP.” during Magento installation is caused because of the missing PHP extension named sodium. The solution is to enable sodium extension.

Detailed steps to solve the issue in a Local XAMPP server are provided below:

• Step 1: Open the XAMPP control panel, and go to Configure > PHP in the Apache module.
  
• Step 2: This will open the php.ini file, where you can find the list of active/inactive PHP extensions. Find extension=sodium, remove the ; sign before it, and save the file. This will enable sodium extension.
  
• Step 3: Restart the web server, and you’re done! The issue will be solved.

This is how you can solve the error in Compat.php while installing Magento 2 on a local server. 😇
