gunicorn 无法启动 python-eve

Question

这里是 settings.py

root@00d72ee95c2d:/var/www/eve-auth# cat settings.py
DOMAIN = {'people': {}}

这里是 run.py

from eve import Eve
app = Eve()

if __name__ == '__main__':
    app.run()

当我独立运行它时它可以工作：

root@00d72ee95c2d:/var/www/eve-auth# python run.py
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

但是当我通过 gunicorn 启动它时无法运行：

我找不到任何关于 gunicorn 和 python-eve 的文档......所以我不知道从哪里开始挖掘。

Answer 1

我从未在 Gunicorn 上运行 Eve。然而，Eve 是 Fl​​ask 的子类，大多数与 Flask 一起工作的东西也适用于 Eve。

根据 Flask documentation，您在 Gunicorn 上运行 Flask/Eve，如下所示：

gunicorn myproject:app

希望这会有所帮助。

Answer 2

问题是Eve使用相对路径查找settings.py，最快的解决方法是使用绝对路径：

import os
from eve import Eve

app = Eve(__name__, settings=os.path.abspath('settings.py'))

if __name__ == '__main__':
    app.run()
