python3.6.8和pymongo4.0.2有bug

[yan1990y]

mongodb是4.0版本，无密码，也能看到启动正常，但是一旦发布任务再消费，就会报错。

The above exception was the direct cause of the following exception:

网上查说pymongo版本有bug，但是pip安装高版本会提示与funboost的版本要求不兼容。

经测试，不仅mongodb作为消息队列的中间件无法使用，连开启消费状态、结果web页面的库也写不进去。但是在show dbs的时候能看到库已经建立了

可以安装高版本pymongo，提示无所谓，自己看文档文档10.0

主要是你还没有说服务端mongo版本，以及mongo连接有没有写错

[yan1990y]

其实我第一句就写了~~服务端是4.0的，连接没错，因为已经看到db已经建立了。我先试试高版本

后来经过测试，发现是因为我用uwsgi部署，设置了processes=4，在4线程的情况下就会出现这个问题。如果改成processes=1或者不用uwsgi，直接单线程运行都是可以的。目前没有彻底解决这个问题，暂时的解决方案是单独把需要用到任务队列的任务单独部署，设置线程为1，然后内部调用。
