aws弹性beanstalk作曲家突然失败

Question

直到今天早上，我已经能够部署我的laravel应用程序而没有任何问题。 我没有使用composer进行任何更改，并且在.ebextensions文件夹中进行了以下设置

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

尝试部署时，实例日志中出现以下错误

[DEBUG] Action for aws-eb-command-handler output: {"status":"FAILURE","api_version":"1.0","truncated":"true","results":[{"status":"FAILURE","msg":"[CMD-AppDeploy/AppDeployStage0/AppDeployPreHook/10_composer_install.sh] command failed with error code 1: /opt/elasticbeanstalk/hooks/appdeploy/pre/10_composer_install.sh\n++ /opt/elasticbeanstalk/bin/get-config container -k app_staging_dir\n+ EB_APP_STAGING_DIR=/var/app/ondeck\n+ cd /var/app/ondeck\n+ '[' -f composer.json ']'\n+ export COMPOSER_HOME=/root\n+ COMPOSER_HOME=/root\n+ '[' -d vendor ']'\n++ /opt/elasticbeanstalk/bin/get-config optionsettings -n aws:elasticbeanstalk:container:php:phpini -o composer_options\n+ PHP_COMPOSER_OPTIONS=--no-dev\n+ echo 'Found composer.json file.

如果删除自我更新呼叫，则会出现此错误

我遇到的任何事情我都没有成功尝试过。 无论部署版本如何，它都会在我的每个实例（甚至是一个不同的项目）上发生。 我可以在本地更新composer，也可以在有问题的服务器上更新ssh并手动进行更新。 我可以部署到今天早上为止，而且我什么都没做，所以我对可能的情况不知所措。 我在运行PHP 5.5的64位Amazon Linux 2014.09 v1.0.9上运行

这似乎与Composer本身有关。 https://github.com/composer/composer/issues/4789在self-update后添加1.0.0-alpha11并添加- namespace: aws:elasticbeanstalk:application:environment option_name: HOME value: /root在option_settings解决了此问题。
