Hi,

I installed GrumPHP with one task, php-cs-fixer, and when commiting a file, it shows the following error.

However when I run php ./vendor/bin/grumphp run it works as expected.

My configuration

parameters:
    git_dir: .
    bin_dir: vendor/bin
    tasks:
      phpcsfixer:
        config_file: .php_cs

• Run GrumpHP:
• git add .
• git commit composer.json "Test"

Result:

[Gitonomy\Git\Exception\RuntimeException]
