Version of install-php-extensions

latest

Error description

I run a docker built with --cache-from and BUILDKIT_INLINE_CACHE on.

Then they get installed again. Is that wanted? Maybe I'm missing something?

This is a false report, it works great, only one uninstalled extension get installed 😓

WARNING Module already installed: amqp

Yep, those are just messages that mean: "You asked me to install amqp, but I won't do it since it's already installed".
