Composer install - extension intl error but phpinfo() says intl enabled

@stoofvlees,

I have just updated to the latest Ubuntu operating system and emphathise about the installation. I think that the CodeIgniter4 installation should be simplified so that the Splash Screen works without having to modify any defaults.

None of the requirements below should be obligatory in order to render the Splash Screen.

PHP version 7.4 or newer is required, with the *intl* extension and *mbstring* extension installed.

The following PHP extensions should be enabled on your server: php-json, php-mysqlnd, php-xml

Folder permissions to be set to 0777 for the writable  path..

I'm convinced that having to delve into the operating system to set the additional requirements is counter-productive. The  very unhelpful Whoops message is very off-putting.

Has anyone time on their hands to create a:

preInstallationTestEnvironment.php?
