python - 安装 redis 时缺少 redis 库

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并且import redis没有错误。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celery -A tasks worker --loglevel=info 在bash中运行时，我得到以下堆栈跟踪（请注意当我运行python 2.7时芹菜路径中的python3 - 我觉得这很重要但不确定如何，或者如何改变）：

Traceback (most recent call last):

    raise ImportError('Missing redis library (pip install redis)')
ImportError: Missing redis library (pip install redis)

运行时 bash 的输出python：

解决方案

更合理的问题是，在 pycharm 中，当您设置解释器时，您给了它错误的路径。您将其设置为 /usr/bin/python3 而不是 python2 的路径
