gunicorn無法啓動蟒蛇前夕

Question

這裏的settings.py

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

而這裏的run.py

from eve import Eve 
app = Eve() 

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

它的工作原理，當我運行它獨立：

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

但失敗當我通過gunicorn啓動時運行：

我找不到關於gunicorn和python-eve的任何文檔......所以我不確定從哪裏挖掘。

Answer 1

我從未在Gunicorn上跑過Eve。然而，Eve是一個Flask子類，與Flask一起工作的大多數東西也適用於Eve。

根據瓶documentation你Gunicorn運行瓶/夏娃這樣的：

gunicorn myproject:app 

希望這有助於。

Answer 2

的問題是，夏娃使用相對路徑來尋找settings.py，最快的解決方法是使用絕對路徑：

import os 
from eve import Eve 

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

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