python - 将 django 应用程序部署到 aws beanstalk 时的 requirements.txt 无效

Question

在我最近一次提交之前，我一直在将我的应用程序部署到 beanstalk 环境中，没有任何问题。

现在我明白了

快照日志是这样说的:

我的 requirements.txt 和以前一样。我也尝试删除 requirements.txt 中的所有内容，但我再次遇到同样的错误，这让我认为问题出在 requirements.txt 运行之前。

我不知道部署的顺序。无论如何，这是我的配置文件:

packages:
  yum:
    libjpeg-devel: '6b'
    zlib-devel: []
    freetype-devel: []


container_commands:
  01_install_mysqldb:
    command: "pip install distribute==0.6.28; pip install mysql-python;"
  02_syncdb:
    command: "python manage.py syncdb --noinput"
    leader_only: true
  03_createadmin:
    command: "python scripts/createadmin.py"
    leader_only: true
  04_collectstatic:
    command: "python manage.py collectstatic --noinput"
  05_migrate_wizards:

  10_migrate_actstream:
    command: "python manage.py migrate actstream --noinput"
    leader_only: true

option_settings:

我遇到了完全相同的问题。唯一对我有用的是(自动)重建我的整个环境。您可以在 AWS 控制台中执行此操作。转到您的环境并单击操作 > 重建环境。这将需要一些时间，之后它会自动重新启动您的应用而不会出现此错误。

更新:

问题不时出现。我发现当 pip 编译 psycopg 时出现问题，这是 postgreSQL 支持所必需的。还没有找到真正的解决方案。
