[L5] "laravel/framework suggests installing" lots of things

Hello!

I've been wrestling with Laravel 5 and Pagoda Box V2 today, and currently have a problem I'm unable to solve so far.

Laravel now deploys to Pagoda Box, and the homepage works. However, after I tried to switch the cache/session driver to Redis, I started getting the error HandleExceptions->fatalExceptionFromError(array('type' => '1', 'message' => 'Class 'Predis\Client' not found', 'file' => '/data/vendor/laravel/framework/src/Illuminate/Redis/Database.php', 'line' => '58')). I did a bit of searching, and it seems that when it deployed to Pagoda Box, I got a bunch of successful installing/cloning messages, but then recommendations to install lots of other things as you can see below.

It seems Predis isn't installed on my local machine either. I've tried running composer clear-cache and composer update, but nothing seems to fix/install any of the suggestions.

Any help is greatly appreciated! Thank you :)
