我知道这个问题有一段时间没有答案，可能已经解决了，但这可以帮助别人。
第一次尝试：
gunicorn --log-file=- (your_project_name).wsgi:application
您会在加载 gunicorn 启动时看到包含其他参数的日志。
在我的例子中，缺少一个包，我安装了那个包并输入了 foward 命令：
sudo systemctl daemon-reload
sudo systemctl restart gunicorn
sudo systemctl enable gunicorn
问题已解决。希望这个回答能帮到你。
我有一个类似的错误，原来是我的 Django 代码中引入的语法错误。
因此，尝试 运行 Django standalone
总是一个好主意
python manage.py runserver
当你突然有一个 Gunicorn "Worker failed to boot" 错误
我正在 Digital Ocean Ubuntu 16.04 VPS 上部署 Django 项目。我使用了 Django 的一键安装，然后替换为我的项目。
问题是服务器 returns 502 Error.

我知道这个问题有一段时间没有答案，可能已经解决了，但这可以帮助别人。 第一次尝试：
gunicorn --log-file=- (your_project_name).wsgi:application
您会在加载 gunicorn 启动时看到包含其他参数的日志。 在我的例子中，缺少一个包，我安装了那个包并输入了 foward 命令：
sudo systemctl daemon-reload
sudo systemctl restart gunicorn
sudo systemctl enable gunicorn
问题已解决。希望这个回答能帮到你。
我有一个类似的错误，原来是我的 Django 代码中引入的语法错误。
因此，尝试 运行 Django standalone
总是一个好主意python manage.py runserver
当你突然有一个 Gunicorn "Worker failed to boot" 错误
