[FIXED] php intl extension missing

Issue

I'm using a Mac Mojave. Installed MAMP. Composer Version 1.8.4 . When trying to create cakePHP project inside the htdocs by using

composer create-project --prefer-dist cakephp/app test

The terminal is giving error

    PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20160303/intl.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20160303/intl.so, 0x0009): dlopen(): file not found: /usr/lib/php/extensions/no-debug-non-zts-20160303/intl.so in Unknown on line 0

  Problem 1
    - cakephp/cakephp 3.7.5 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/cakephp 3.7.4 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/cakephp 3.7.3 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/cakephp 3.7.2 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/cakephp 3.7.1 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - cakephp/cakephp 3.7.0 requires ext-intl * -> the requested PHP extension intl is missing from your system.
    - Installation request for cakephp/cakephp 3.7.* -> satisfiable by cakephp/cakephp[3.7.0, 3.7.1, 3.7.2, 3.7.3, 3.7.4, 3.7.5].

  To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Doing some research on the internet, I tried to enable the intl extension in the php files in etc/php.ini and also the php.ini file inside the MAMP folder.

I am stuck on this for a whole day and had not been able to make any progress.

Please help me.

Solution

Your problem is NOT that the extension is not enabled (it IS).

Your problem is this:

dlopen(): file not found: /usr/lib/php/extensions/no-debug-non-zts-20160303/intl.so

This path and/or file just does not exist. Check the ini for the "extension_dir" folder setting. Locate the proper folder and adjust the "extension_dir" folder setting accordingly.
