After installing CodeIgniter 4 when you run the app then you will get an error like this:
Whoops! We seem to have hit a snag. Please try again later
And in cmd line when run composer update you see something similar to this output below:
Problem 1
– codeigniter4/framework[4.0.0, …, v4.4.4] require ext-intl * -> it is missing from your system. Install or enable PHP’s intl extension.
– Root composer.json requires codeigniter4/framework ^4.0 -> satisfiable by codeigniter4/framework[4.0.0, …, v4.4.4].
To enable extensions, verify that they are enabled in your .ini files:

You can also run `php –ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `–ignore-platform-req=ext-intl` to temporarily ignore these required extensions.
The solution: This method works better and doesn’t have the message above.
