Fatal error: Interface 'Symfony\Component\HttpKernel\Log\LoggerInterface' not found..

[fractalf]

This file seems to be missing

./vendor/symfony/http-kernel/Log/LoggerInterface.php

I followed the instructions here exactly:
http://gaspaio.github.io/gearmanui/

I got the same error

PHP Fatal error:  Interface 'Symfony\\Component\\HttpKernel\\Log\\LoggerInterface' not found in MyWebRoot/vendor/symfony/monolog-bridge/Logger.php on line 23

It seems that it is missing the symfony component in composer.json.

I tried to add an entry "symfony/symfony": "2.7.*" in composer.json, the dependence issues is fixed. But the routing is still wrong.

Adding "symfony/symfony": "2.7.*" in composer.json solved the issue in my case.
