我的Procfile是标准web: gunicorn opportunis.wsgi --log-file -，我的设置是：

settings
|_ __init__.py
|_ locals_settings.py
|_ sever_settings.py

在__init__.py我有：

# -*- coding: utf-8 -*-
import os

var = os.getenv('IS_SERVER', 0)

if bool(var):
    try:
        from .server_settings import *
    except ImportError:
        from .locals_settings import *

locals_settings和server_settings之间的差异是debug off，DATABASES和dj_database_url的一些配置。在wsgi.py我有这段代码：

import os
var = os.getenv('IS_SERVER', 0)

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

if bool(var):
    try:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings.server_settings")
    except ImportError:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings.locals_settings")

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

我做了什么或没有做过失败？

答案 0 :(得分：1)

看起来你错过了一些gunicorn试图导入的模块。这通常是因为您没有安装所有必要的要求。通常，如果您已有requirements.txt文件，则可以使用以下命令来安装项目的要求：

pip install -r requirements.txt

如果您使用的是虚拟环境，您必须确保gunicorn正在使用您已设置的虚拟环境，这会变得稍微复杂一些。

我刚刚注意到原帖的一些更新。作为一个FYI-永远不会达到这里的除外条款：

if bool(var):
    try:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings.server_settings")
    except ImportError:
        os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings.locals_settings")

setdefault只会设置环境变量，在使用之前不会触发任何导入。
