python - django-elasticsearch错误: [Errno -2] Name or service not known

Question

我正在尝试安装由其他人开发的应用程序，并且在运行manage.py命令时出现此错误，我不明白。我想知道是否有人可以告诉我先去哪里调查 - 谢谢。

编辑

根据要求添加了manage.py

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault('DEPLOY_ENV', 'local')
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'core.settings.%s' % os.environ['DEPLOY_ENV'])

    from django.core.management import execute_from_command_line  # noqa
    execute_from_command_line(sys.argv)

正如 Goran 所说，我试图连接到 elasticsearch:9200 但测试 localhost:9200
