supervisord：

[supervisord]
nodaemon=true

[program:flask-uwsgi]
command=/bin/bash -c "exec uwsgi --ini /etc/flask-uwsgi/flask-uwsgi.ini -DFOREGROUND"

烧瓶uwsgi.ini：

[uwsgi]
chdir = /home/ubuntu/canonicaliser_api

错误信息：

如果我改为这样运行，则效果很好。 所以uwsgi设置可以不错：

CMD uwsgi --ini /etc/flask-uwsgi/flask-uwsgi.ini

我认为这只是您需要提供完整路径并摆脱-DFOREGROUND （这不是-DFOREGROUND标志）。 尝试：

command=/usr/local/bin/uwsgi --ini /etc/flask-uwsgi/flask-uwsgi.ini
