python - Elastic Beanstalk 无法安装包

Question

我正在尝试在 AWS Elastic Beanstalk 上部署我的应用程序。我收到此错误，完全看不出问题出在哪里。

下面是 .ebextensions/mysite-env.config 中的代码

packages:
  yum:
    python-devel: []
    postgresql-devel: []

container_commands: 
  01_syncdb:
    command: "django-admin.py syncdb --noinput"
    leader_only: true
  02_createadmin: 
    command: "scripts/createadmin.py"
    leader_only: true

option_settings: 
  - option_name: WSGIPath
    namespace: "aws:elasticbeanstalk:container:python"
    value: "mysite/wsgi.py"
  - option_name: DJANGO_SETTINGS_MODULE
    value: "mysite.settings"

经过几次尝试，我想通了一些事情

1. 上面的配置文件似乎在 requirements.txt 出现在根目录之后运行
2. 无法安装那些包(如上所述)，但我可以通过进入 EC2 实例的 ssh 来安装(奇怪)

[1] 的问题在于，要安装 psycopg2，我需要上述包。那么，我该如何先安装它们呢？

当我运行这些设置时，出现以下错误:

[2014-11-19T09:45:19.819Z] INFO  [6703]  - [CMD-AppDeploy/AppDeployStage0/EbExtensionPreBuild] : Activity execution failed, because: command failed with error code 1: Error occurred during build: Yum does not have postgresql-devel available for installation (Executor::NonZeroExitStatus)

然后，我使用了以下设置

套餐: 百胜: python 开发:[] 易于: postgresql-devel: []

然后我收到以下错误:

[2014-11-19T09:47:54.271Z] ERROR [6789]  : Command execution failed: [CMD-AppDeploy/AppDeployStage0/EbExtensionPreBuild] command failed with error code 1: Error occurred during build: [Errno 2] No such file or directory (ElasticBeanstalk::ActivityFatalError)
    at /opt/elasticbeanstalk/lib/ruby/lib/ruby/gems/2.1.0/gems/beanstalk-core-1.0/lib/elasticbeanstalk/activity.rb:189:in `rescue in exec'
    ...
caused by: command failed with error code 1: Error occurred during build: [Errno 2] No such file or directory (Executor::NonZeroExitStatus)

当我可以直接从 ssh 安装这些包时，自动化有什么问题？我的设置有什么问题？

在 yum 语句中使用 postgresql93-devel 因为他们已经更新了包名

packages:
  yum:
    python26-devel: []
    postgresql93-devel: []
