Conflict with redis extension using v2.18.0 shim

[mdeboer]

I suddenly ran into an issue upgrading GrumPHP from v2.17.0 to v2.18.0 using phpro/grumphp-shim. When I run vendor/bin/grumphp or vendor/bin/grumphp.phar, I get an error from the "Box Requirements Checker":

Fix the following mandatory requirements:
=========================================

 * The package "symfony/cache" conflicts with the extension "redis". You need to disable it in order to run this application.

Now please note that I'm using the shim version here, so this is not some conflict with my project's dependencies.

I am presuming that humbug/box is being used to build the PHAR and apparently it is running a requirements checker before anything is run from the PHAR itself.

Apparently the latest changes to the composer.json have led to a false-positive as I'm not aware of any conflict with the redis extension. In fact, the Symfony documentation mentions this:

Requirements: At least one Redis server must be installed and running to use this adapter. Additionally, this adapter requires a compatible extension or library that implements \Redis, \RedisArray, RedisCluster, \Relay\Relay, \Relay\Cluster or \Predis.

Currently downgrading to v2.17.0 fixes it for me, but hopefully a fix can be found.

It is a box issue: it doesn't check the version constraints correctly.

@veewee ah thanks! Sorry, didn't see there was a separate repo for the shim. I'll close this 👍🏻
