PHP Fatal error: Interface 'PHP_CodeSniffer_Sniff' not found

Hi there:

I am getting a fatal error when attempting to use your standard while running phpcs from the command line.

Here is the command I'm using:

$  phpcs --standard=Laravel /Users/govinda/Sites/mysite/app/Models/Blog.php

PHP Fatal error:  Interface 'PHP_CodeSniffer_Sniff' not found in /Users/govinda/.composer/vendor/pragmarx/laravelcs/Standards/Laravel/Sniffs/ControlStructures/ControlSignatureSniff.php on line 12

In contrast, phpcs seems to work fine with PSR2. For example, the following command outputs normally:

$  phpcs --standard=PSR2 /Users/govinda/Sites/mysite/app/Models/Blog.php

Some of my system info:

PHP_CodeSniffer version 3.1.1 (stable) by Squiz (http://www.squiz.net)
PEAR Version: 1.10.5
PHP Version: 7.1.8
Zend Engine Version: 3.1.0
Running on: Darwin Govindas-iMac.local 16.7.0 Darwin Kernel Version 16.7.0: Thu Jun 15 17:36:27 PDT 2017; root:xnu-3789.70.16~2/RELEASE_X86_64 x86_64

Is this is a namespace issue?
