【问题描述】：

我第一次尝试将 django 应用程序部署到弹性 beanstalk。该应用程序使用 django 频道。

这些是我的配置文件：

option_settings:  
  aws:elasticbeanstalk:container:python:     
    WSGIPath: "dashboard/dashboard/wsgi.py"
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: "dashboard/dashboard/settings.py"
    PYTHONPATH: /opt/python/current/app/dashboard:$PYTHONPATH

  aws:elbv2:listener:80:
    DefaultProcess: http
    ListenerEnabled: 'true'
    Protocol: HTTP
    Rules: ws
  aws:elbv2:listenerrule:ws:
    PathPatterns: /websockets/*
    Process: websocket
    Priority: 1
  aws:elasticbeanstalk:environment:process:http:
    Port: '80'
    Protocol: HTTP
  aws:elasticbeanstalk:environment:process:websocket:
    Port: '5000'
    Protocol: HTTP

container_commands:
  00_pip_upgrade:
    command: "source /opt/python/run/venv/bin/activate && pip install --upgrade pip"
    ignoreErrors: false
  01_migrate:
    command: "django-admin.py migrate"
    leader_only: true
  02_collectstatic:
    command: "django-admin.py collectstatic --noinput"
  03_wsgipass:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'

当我运行 eb create django-env 时，我得到以下日志：

错误非常模糊，我不知道自己做错了什么。

【问题讨论】：

您是否从实例中获得了完整的日志？也许他们有更多信息？

@Marcin 我不确定如何获取更多日志。当我转到us-east-2.console.aws.amazon.com/elasticbeanstalk/… 时，我什至没有看到列出的任何环境。

所以环境创建失败，即使消息说“创建环境操作完成”？和实例？如果你去ec2控制台？

@Marcin 好吧，我的错，我看到的是 us-east-2 而不是创建环境的 us-west-2。现在会尝试检查日志，但是日志文件很多

【参考方案1】：

我遇到了类似的问题。我使用 psycopg2-binary 而不是 psycopg2 并创建了一个新环境。现在健康状况正常

【讨论】：

你到底是怎么切换的？

【参考方案2】：

由于这引起了一些关注，我建议您在 aws 控制台上检查您的 Elastic Beanstalk 日志，因为该错误是完全通用的并且可能是任何错误。我建议主要检查 cmd 执行和活动日志。

就我而言，这是因为我在 requirements.txt 中列出了以下内容，并且它们无法在 EC2 上安装：

mkl-fft==1.1.0
mkl-random==1.1.0
mkl-service==2.3.0
pypiwin32==223
pywin32==228

从 requirements.txt 中删除这些修复了问题
