Problem when deploy wordpress app

[gwmoura]

I have a wordpress app running normally, but when I tryed update it, I receive this error:

The error occur in this line - https://github.com/tsuru/platforms/blob/master/php/deploy.py#L108

if os.system('cd %s && %s install' % (self.application.get('directory'), composer_phar)) != 0:
                raise InstallationException('Unable to install composer dependencies')

Accessing the container and following this steps to simulate the error, I receive this error:

Running with sudo the script is executed normally:

$ python -c 'import os; os.system("cd /home/application/current && sudo ./composer.phar install")'
Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted

I think if we change os.system('cd %s && %s install' % (self.application.get('directory') to os.system('cd %s && sudo %s install' % (self.application.get('directory'), composer_phar)), composer_phar))` this problem is resolved.

@gwmoura, you had progress with this?

@gwmoura could you check if this still happen? I've updated php platform and tested composer with success.
