gunicorn 无法发射 python-eve

Question

这是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()

它在我运行独立时工作：

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 启动它时运行失败:

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

Answer 1

我从不运行 Gunicorn 上的 Eve。然而，Eve 是 Flask 的子类，大多数适用于 Flask 的东西也适用于 Eve。

根据 Flask documentation 你在 Gunicorn 上运行 Flask/Eve 是这样的：

gunicorn myproject:app

希望对您有所帮助。

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()
