我无法“ eb部署”。在部署的构建后阶段，某些事情会崩溃。
似乎dnspython == 1.15.0软件包没有安装，这可能以某种方式破坏了部署。
我认为这与pymongo有关。
控制台中给出的错误是：
2018-09-26 19:03:56 INFO Deploying new version to instance(s).

You are using pip version 9.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我的.ebextensions/db-migrate.config说：
container_commands:
01_migrate:
command: "django-admin.py migrate"
leader_only: true
option_settings:
aws:elasticbeanstalk:application:environment:
DJANGO_SETTINGS_MODULE: cauradata.settings
我尝试从db-migrate.config文件中删除01_migrate，但这不起作用。
（即删除此位：）
container_commands:
01_migrate:
command: "django-admin.py migrate"
leader_only: true
我曾尝试像这样在db-migrate.config中单独添加软件包。这不会改变任何东西。
