在gunicorn日志中,我得到了错误:

更新:
我修改了/vev/lib/python3.6/site-packages/gunicorn/config.py中的gunicorn config.py文件
BASE_DIR = "/path/to/base/dir/"
sys.path.append(BASE_DIR)
bind = '127.0.0.1:8000'
backlog = 2048
import multiprocessing
workers = multiprocessing.cpu_count() * 2 + 1
worker_class = 'gevent'
worker_connections = 1000
timeout = 300
keepalive = 2
然后修改了我的supervisor/conf/gunicorn.conf文件,如下所示:
[program:gunicorn]
directory=/home/ubuntu/mysite
command=/home/ubuntu/exo/bin/gunicorn --config /home/ubuntu/venv/lib/python3.6/site-packages/gunicorn/config.py unix:/home/ubuntu/mysite/app.sock mysite.wsgi:application
autostart=true
autorestart=true
stderr_logfile=/var/log/gunicorn/gunicorn.err.log
stdout_logfile=/var/log/gunicorn/gunicorn.out.log
[group:guni]
programs:gunicorn
这仍然给我同样的错误。我甚至不确定gunicorn配置文件是否是添加修改的正确文件,但在这一点上,我已经没有东西可以尝试了,也许一个新的视角可以解决这个问题,或者我也愿意接受任何可能有人知道的替代品最后我发现了,希望这个答案能对有同样问题的人有所帮助 1) 需要按如下方式安装gevent:
python3 -m pip install gevent
2) 在env/python/site-packages/gunicorn/config.py中添加以下内容:
BASE_DIR = "/path/to/base/dir/"
sys.path.append(BASE_DIR)
bind = '127.0.0.1:8000'
backlog = 2048
import multiprocessing
workers = multiprocessing.cpu_count() * 2 + 1
worker_class = 'gevent'
worker_connections = 1000
timeout = 300
keepalive = 2
3) 然后在gunicorn.conf中,必须确保引用config.py文件的路径
