【问题描述】：

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

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "queuearoo.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

我正在使用 puTTY 从远程服务器访问它并收到如下错误

Traceback (most recent call last):

【问题讨论】：

用“pip install redis”安装
你的本地机器上安装了redis吗？

标签： django python-3.x python-2.7

【解决方案1】：

你只需要使用这个命令安装redis：

pip install redis

还请注意，您使用的是虚拟环境，因此您需要先激活它：

source /home/devbase/env/local/bin/activate

【讨论】：

安装 redis 和 djorm_pgtrgm 后，它仍然向我显示这样的错误 from django.db import backend ImportError: cannot import name backend
是的，django/db/__init__.py 或 django/db/ 中没有定义后端名称。您要导入的是backends。见github.com/django/django/tree/master/django/db/backends
