Composer install命令在我的计算机上本地工作正常:

• 使用包信息加载composer存储库
• 从锁定文件安装依赖项
• 无需安装或更新
• 生成自动加载文件

当我通过ssh连接到ubuntu服务器,并运行相同的命令,我得到了这个.

PHP Fatal error:  Class 'Composer\Installers\Installer' not found in phar:///usr/local/bin/composer/src/Composer/Installer/InstallerInstaller.php on line 102

Fatal error: Class 'Composer\Installers\Installer' not found in phar:///usr/local/bin/composer/src/Composer/Installer/InstallerInstaller.php on line 102

我按照这里的说明操作两台机器:https: //github.com/composer/composer/blob/master/README.md

我在这里缺少一些依赖项？我无法弄清楚为什么会出错.

编辑:这是.json(项目是symfony 1.4,也添加了标签)

{
  "minimum-stability": "dev",
  "require"     : {
    "snappy/sfSnappyPlugin": "*"
  },
  "repositories": [
    {
      "type": "git",
      "url": "https://github.com/FloranBrutel/sfSnappyPlugin.git"
    }
  ]
}

Edit2:AWS服务器上php -v的输出
