【问题描述】：

我安装了 redis 和 celery python 库。我已经安装并运行了 redis 服务器。使用 bash 我可以运行 python 和 import redis 而不会出错。我安装了 python-celery-common。我正在使用 PyCharm 和 WSL。出于某种原因，当我创建 tasks.py 并尝试在 bash 中运行 celery -A tasks worker --loglevel=info 时，我得到以下堆栈跟踪（请注意当我运行 python 2.7 时 celery 路径中的 python3 - 我觉得这很重要但不确定如何或如何改变）：

Traceback (most recent call last):

  File "/usr/lib/python3/dist-packages/kombu/transport/redis.py", line 1009, in __init__
    raise ImportError('Missing redis library (pip install redis)')
ImportError: Missing redis library (pip install redis)

当我运行 python 时来自 bash 的输出：

Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)

Type "help", "copyright", "credits" or "license" for more information.

pip freeze的输出

【问题讨论】：

为什么不使用虚拟环境来避免这些问题呢？看起来您需要更改操作系统中的默认 python 版本（如果您仍想全局使用它）
你应该重启应用

【解决方案1】：

更合理的问题是，在 pycharm 中，当你设置解释器时，你给了它错误的路径。你将它设置为 /usr/bin/python3 而不是 python2 的路径
