aws彈性beanstalk作曲家突然失敗

Question

直到今天早上，我已經能夠部署我的laravel應用程序而沒有任何問題。 我沒有使用composer進行任何更改，並且在.ebextensions文件夾中進行了以下設置

commands:
    001_update_composer:
        command: export COMPOSER_HOME=/root && /usr/bin/composer.phar self-update

option_settings:
    - namespace: aws:elasticbeanstalk:application:environment
      option_name: COMPOSER_HOME
      value: /root

嘗試部署時，實例日志中出現以下錯誤

如果刪除自我更新呼叫，則會出現此錯誤

我遇到的任何事情我都沒有成功嘗試過。 無論部署版本如何，它都會在我的每個實例（甚至是一個不同的項目）上發生。 我可以在本地更新composer，也可以在有問題的服務器上更新ssh並手動進行更新。 我可以部署到今天早上為止，而且我什么都沒做，所以我對可能的情況不知所措。 我在運行PHP 5.5的64位Amazon Linux 2014.09 v1.0.9上運行

這似乎與Composer本身有關。 https://github.com/composer/composer/issues/4789在self-update后添加1.0.0-alpha11並添加- namespace: aws:elasticbeanstalk:application:environment option_name: HOME value: /root在option_settings解決了此問題。
