Question

我有一个不错的Flask应用程序，该应用程序使用flask-rq2来运行后台任务-一切都在本地运行良好，但是当我尝试投入生产时遇到了麻烦。一切都在Ubuntu 18.04服务器上的虚拟环境中运行，我正在使用gunicorn运行Flask应用程序，并使用supervisor进行管理。 Flask应用程序运行正常，但RQ工作人员启动并快速失败，并出现以下错误，使我似乎不在虚拟环境中。

KeyError: <flask.cli.ScriptInfo object at 0x7f2c8ca77828>

我尝试通过几种不同的方式为主管设置配置文件，但目前已确定以下内容：

rq.conf

[program:rq]
directory=/home/ceams_admin/ceams
command=sh boot-workers.sh
process_name=%(program_name)s-%(process_num)s
numprocs=1
autostart=true
autorestart=true
stopsignal=TERM
stdout_logfile=/var/log/redis/redis_stdout.log
stderr_logfile=/var/log/redis/redis_stderr.log
stderr_logfile_maxbytes=10MB
stdout_logfile_maxbytes=10MB

其中boot-workers.sh是：

#!/bin/bash
set -eu

. venv/bin/activate
flask rq worker

关于如何更好地调试或如何启动rq的任何建议都很棒！

使用超级用户运行flask-rq2
