Django + mod_wsgi + apache2: ImportError: No module named <project>

Question

我正试图弄清关于在我的 django 项目上运行ning 任何 "migrate" 命令的问题。我在虚拟环境中部署了一个 Django 应用程序，并且使用 mod_wsgi 和 apache2，该应用程序在 www.mysite.com/test/simulatore 上正常运行。当我编辑模型时出现问题，所以我不得不运行

python manage.py makemigrations

经过一些初步的故障排除后，我想我已经在 wsgi.py
上隔离了问题如果我尝试（从我的 virtualenv）尝试运行命令

python -i /home/carma/mycarma_test/mycarma/mycarma/wsgi.py

这是结果

ImportError: No module named '”mycarma'

如您所见，模块 mycarma（这是项目名称）用单引号报告，并且只是初始双引号

ImportError: No module named '”mycarma'

这告诉我（我认为）某处存在配置问题，传递了错误的参数，但我找不到哪里。这是我的设置：

文件 wsgi 在 mycarma/mycarma

import os
import sys

from django.core.wsgi import get_wsgi_application

DJANGO_PATH = os.path.join(os.path.abspath(os.path.dirname(__file__)), '..')
sys.path.append(DJANGO_PATH)
sys.path.append('/home/carma/mycarma_test')
sys.path.append('/home/carma/mycarma_test/mycarma')
print(sys.path)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mycarma.settings")

application = get_wsgi_application()

请注意，我添加了两个追加和打印是为了 test/troubleshoot。但也没有他们没有运气。 settings.py

ROOT_URLCONF = 'mycarma.urls'
STATIC_URL = '/static/'
STATIC_ROOT = '/home/carma/mycarma/static'

Apache2 配置文件

谢谢。

编辑：发现问题 在开发 bin/activate 脚本中

DJANGO_SETTINGS_MODULE=”carma.test_settings”

使用了一些奇怪的双引号。修改后一切正常。

Answer 1

我很确定那是因为您的 INSTALLED_APPS django 配置中有额外的双引号。当 django 引导并尝试加载您的所有应用程序但无法找到它时，就会发生这种情况。
