Redis:ImportError,尽管满足依赖关系

我正在检查在虚拟环境中使用Redis Queue的情况。目录结构如下:

Scripts-V3 (Virtualenv is at this level)
├── RQ
│   ├── countwords.py
│   └── queue.py

这与documentation中给出的示例相同。

queue.py是:

from redis import Redis
from rq import Queue
from countwords import count_words_at_url
import time

# Tell RQ what Redis connection to use
redis_conn = Redis()
q = Queue(connection=redis_conn)  # no args implies the default queue

# Delay execution of count_words_at_url('http://nvie.com')
job = q.enqueue(count_words_at_url, 'http://nvie.com')
print(job.result)   # => None

# Now, wait a while, until the worker is finished
time.sleep(2)
print(job.result) 

我已检查是否已安装必需的软件包(redis,rq):

> pip3 install rq                                                          
Requirement already satisfied: rq in /Users/abc/Work/driver-pic-orient/venv/lib/python3.7/site-packages (1.0)
Requirement already satisfied: redis>=3.0.0 in /Users/abc/Work/driver-pic-orient/venv/lib/python3.7/site-packages (from rq) (3.2.1)
Requirement already satisfied: click>=5.0 in /Users/abc/Work/driver-pic-orient/venv/lib/python3.7/site-packages (from rq) (7.0)

但是,当我运行python3 queue.py时,它会失败:

Traceback (most recent call last):

    from rq import Queue
ImportError: cannot import name 'Redis' from 'redis' (/Users/abc/Work/driver-pic-orient/venv/lib/python3.7/site-packages/rq/__init__.py)

我不明白为什么。怎么了?

答案 0 :(得分:0)

这个问题是交叉发布的,并且已经在rq's Github page上得到了回答:

请在追溯中查看此处

File "/Users/shubhamrathi/Work/driver-pic-orient/venv/lib/python3.7/site-packages/redis/_compat.py", line 106, in <module>
    from queue import Queue
     

您的本地目录中有一个名为queue.py的文件。它会   引起冲突。我认为将queue.py重命名为<file_name>.py   工作。

基本上,您自己的queue阴影Python's own queue
