ImportError: Missing redis library (pip install redis) about redisbeat HOT 12 CLOSED

ok, would you mind try execute python command to enter python dynamic interpreter enviroment, and then input:

import redis

from redisbeat.

Yes, I input import redis via python dynamic interpreter environment, it pause for keyboard input >>>

from redisbeat.

It seems your redis library install is ok，would you mind show all the output of command for celery worker -A tasks -l info and the all output of command python for your environment?

from redisbeat.

我看到你在深圳，原谅我发中文了哦，你是让我贴出所有的报错吗？这个是安装redis包后在/example路径下输入celery worker -A tasks -l
```

如果不介意的话，把直接在命令行敲 python 命令的所有输出也贴一下，谢谢。

您最后一句的意思是让我也贴出python的报错吗？

问题很显然，你的环境管理没做好，你的 redis 是安装在 Python2 下面，而执行 Celery 是在 Python3 环境下面，至于怎么解决这个问题，搜索引擎可以帮助到你。

好的，谢谢你。

嗨，抱歉不得不再次打扰，python3环境下已安装redis，在命令行输入 celery worker -A tasks -l 后，还是没有成功启动celery worker.................就是一直重复显示红色字体 [2018-01-25 10:31:54,168: ERROR/MainProcess] consumer: Cannot connect to redis://localhost:6379//: . Trying again in 2.00 seconds...

这个提示也很明显。。

请确认你本地的 redis 是起来的。。最简单的方法就是：redis-cli

from redisbeat.

您好，再次麻烦您，我输入redis-cli后，它提示的连接拒绝。。。

`Could not connect to Redis at 127.0.0.1:6379: Connection refused

not connected>`

from redisbeat.

哈哈，这样的问题原来网络上有很多，搜索到了，请忽略我，再次感谢
