huey在windows下使用的坑

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

4.如果使用thread方式则没有问题

python huey_consumer.py -w 2 -k thread demo.huey
