📝 Title: How to Fix the "dyld: Library not loaded" Error After Installing Node with Homebrew on Mac

Introduction: Have you recently installed Node using Homebrew on your Mac, only to encounter an unexpected error when trying to run PHP? 😱 Don't worry, you're not alone! Many users have reported facing the "dyld: Library not loaded" error, specifically referring to the missing library file "/usr/local/opt/icu4c/lib/libicui18n.62.dylib". In this blog post, we'll explore the common issues behind this problem and provide you with easy solutions to resolve it. 😊

Understanding the Problem: After installing Node using Homebrew on Mac (Mojave), some users have experienced a disruption in their PHP functionality. The core issue arises when the PHP binary attempts to locate a particular ICU library, but fails due to its absence. This missing library file, libicui18n.62.dylib, is closely related to the International Components for Unicode (ICU) framework. When PHP tries to access this library and fails, it triggers the "dyld: Library not loaded" error.

Possible Solutions: Here are some easy-to-follow solutions to get your PHP up and running smoothly again:

1. Check for conflicting installations: Confirm whether you have multiple versions of PHP or ICU4C installed. In the Terminal, run the following commands:

   brew list | grep php brew list | grep icu4c

   If you find multiple versions, you can choose to uninstall them and keep a clean installation using the brew uninstall command.

2. Reinstall the ICU4C package: If you have confirmed that ICU4C is indeed installed, reinstalling it might resolve the issue. Execute the following commands:

   brew reinstall icu4c

   Once the reinstallation is complete, try running php -v again to verify if the error has been resolved.

3. Check PHP configuration: Occasionally, the PHP configuration might not be properly updated after installing Node via Homebrew. Open your PHP configuration file (php.ini) and ensure the following lines are present and uncommented:

   extension_dir = "<your_php_extension_directory>" extension=intl

   Save the file, restart your web server, and test if PHP is working as expected.
