Local php server error

I’ve downloaded the starterkit and am trying to run php -S localhost:8000 kirby/router.php in the terminal. But then I get:

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicuio.67.dylib
Referenced from: /usr/local/bin/php
Reason: image not found
Abort trap: 6

I’ve used Kirby before, but never had this problem. Can anyone help?

What I finally did was remove PHP from my machine and re-install it. It works now.
