Building failing at Travis-CI due to composer command call - php

Question

I am trying to build my PHP project at Travis-CI but I'm getting an error when he tries to execute a composer command. The build log of my project at Travis-CI:

This job is running on container-based infrastructure, which does not allow use of 'sudo', setuid and setguid executables.
If you require sudo, add 'sudo: required' to your .travis.yml

The command "composer self-update" failed and exited with 127 during .
Your build has been stopped.
I think the problem is here:
$ composer self-update
/home/travis/build.sh: line 41: composer: command not found
My .travis.yml file:
language: php
php:

- 5.5
- 5.6
- hhvm
- hhvm-nightly
before_script:
- composer self-update
- composer install --prefer-source --no-interaction --dev
I am new to Travis-CI and what I see is that composer is not installed or not working. When I read the Travis-CI documentation for PHP projects, they say that composer are available.
From the docs:
Note that we update composer every time we update the PHP build
environment, which is every 30-60 days. Because composer has a
time-based update warning, you may see messages such as this, which
may be safely ignored:
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/home/travis/.phpenv/versions/5.6/bin/composer self-update" to get the latest version.
You can also install Composer packages into the Travis CI PHP
environment. The composer command comes pre-installed, use the
following:
composer install
Maybe I am missing some configuration, but I can't figure what configuration is that.

The problem here is that your build language was set to ruby - for whatever reason. A ruby env doesn't have Composer pre-installed and your command fails.
You find the entry at the first few lines of the Travis build log.
Your composer.json and .travis.yml are allright.
In other words: you requested a PHP env with Composer.
But Travis didn't recognize this.
It's a rather strange issue and maybe it's only temporary.
Please check the file permissions - that's my only guess.
Else you might decide to jump on IRC and ask the Travis guys or file a bug.
