本文解决了一个在启动Celery worker时遇到的SyntaxError问题，通过卸载旧版本并安装指定版本4.4.7的Celery成功解决了问题。

问题描述：

启动worker，执行命令 E:\HttpRunnerManager>python manage.py celery -A HttpRunnerManager worker --loglevel=info

报错 SyntaxError: invalid syntax

  File "C:\Users\Administrator\AppData\Roaming\Python\Python37\site-packages\celery\concurrency\prefork.py", line 20, in <module>
    from celery.concurrency.base import BasePool
  File "C:\Users\Administrator\AppData\Roaming\Python\Python37\site-packages\celery\concurrency\base.py", line 21, in <module>
    from celery.utils import timer2
  File "C:\Users\Administrator\AppData\Roaming\Python\Python37\site-packages\celery\utils\timer2.py", line 19
    from kombu.async.timer import Entry, Timer as Schedule, to_timestamp, logger
                   ^
SyntaxError: invalid syntax

问题解析：

排除脚本语法问题、路径问题、pip安装目录问题，那就是celery版本的问题了

解决方法：

1、使用pip list 可查看celery版本

2、卸载当前的celery版本，卸载命令：pip uninstall celery

3、安装指定版本4.4.7，安装命令：pip install celery==4.4.7

E:\HttpRunnerManager>pip uninstall celery
Found existing installation: celery 3.1.26.post2
