在windows上使用huey会有坑如下。
redis，phthon环境已经安装好。
安装好huey后，使用如下实例：
1.demo.py 任务worker文件，简单的加法
from config import huey
@huey.task()
def add(a, b):
return a + b
2.直接运行worker
python huey_consumer.py -w 1 -k process demo.huey
使用process模型就会报错

3. git上已经有报告
https://github.com/coleifer/huey/issues/2084.如果使用thread方式则没有问题
python huey_consumer.py -w 2 -k thread demo.huey
