在经历了很多障碍之后，我终于将我的代码上传到 AWS Beanstalk，我希望有人可以帮助我解决下一个我认为没有解决方案的障碍。
在我上传(使用'git aws.push')之后，它总是会失败。然后我查看了日志，似乎(作为菜鸟)问题是这样的:
'Target WSGI script not found or unable to stat: /opt/python/current/app/topdish'
我认为这确实是正确的，我希望它应该位于:'/opt/python/ondeck/app/topdish/wsgi.py'
我不知道如何配置它，因为我认为我已经在“.ebextensions”中的“topdish.config”中正确配置了它。
container_commands:
01_migrate:
command: "python manage.py syncdb --noinput"
leader_only: true
option_settings:
- namespace: aws:elasticbeanstalk:container:python
option_name: WSGIPath
value: topdish/wsgi.py
- option_name: DJANGO_SETTINGS_MODULE
value: topdish.settings
我在日志中看到的另一个问题是:
'[2014-11-26T23:11:00.070Z] INFO [4168] - [CMD-AppDeploy/AppDeployStage0/EbExtensionPostBuild] : Activity execution failed, because: command failed with error code 1: Error occurred during build: Command 01_migrate failed (Executor::NonZeroExitStatus)'
可能相关，也可能不相关。

请您参考如下方法:
我认为 'Target WSGI script not found or unable to stat:/opt/python/current/app/topdish' 错误消息是因为您的 container_commands 不成功;只有在成功完成所有 container_commands 之后，部署 Hook 才会将应用程序从 /ondeck 复制到 /current。
作为测试，尝试在您的 01_migrate 容器命令的 leader_only: true 之后的新行中添加 ignoreErrors: true。您的应用程序应该部署，但 syncdb 当然不会运行。
container_commands:
01_migrate:
command: "python manage.py syncdb --noinput"
leader_only: true
ignoreErrors: true
然后尝试输入 python 和 manage.py 的完整路径，没有 ignoreErrors:
container_commands:
01_migrate:
command: "/opt/python/run/venv/bin/python /opt/python/ondeck/app/manage.py syncdb --noinput"
leader_only: true
或者可能:
container_commands:
01_migrate:
command: "/opt/python/run/venv/bin/python26 /opt/python/ondeck/app/manage.py syncdb --noinput"
leader_only: true
