puppet drush composer安装失败

Question

我正在尝试使用vagrant 1.7.4和puppet 4.2.1配置VM。在我安装drush时，一切看起来都不错。

class tools {

  # package install list
  $packages = [
    "curl",
    "vim",
    "htop",
    "git-core"
  ]

  # install packages
  package { $packages:
    ensure => present,
    require => Exec["apt-get update"]
  }

  exec { 'composer-install':
    command => 'curl -sS https://getcomposer.org/installer | php && sudo mv composer.phar /usr/local/bin/composer',
    path    => '/usr/bin:/usr/sbin',
    require => Package['curl'],
  }

  exec { 'drush-install':
    command => 'composer global require drush/drush:dev-master',
    environment => ["COMPOSER_HOME=/usr/local/bin/composer"],
    path    => '/usr/bin:/usr/local/bin:~/.composer/',
    require => Exec['composer-install']
  }

}

Composer安装成功但是drush失败。以下是执行的操作日志：

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.

稍后编辑：

添加--verbose到composer命令：

我做错了吗？
