Django:'Module'对象没有属性'__file__'

Question

我正在Windows机器上设置一个新的开发环境,在成功安装Python和django之后,我在新机器上克隆了我的存储库.

manage.py syncdb成功运行后,我跑了manage.py runserver,但击中localhost:8000了标题上的错误.我跑了django-admin.py startproject testproject,manage.py runserver从那里跑了,那个项目加载得很好,所以我想我可能已经排除了我的django安装,但我需要在这里进行下一步.

这是我的应用程序中的堆栈跟踪炸弹.你能给我的任何帮助将不胜感激.

Exception Value: 'module' object has no attribute '__file__'

Answer 1

导入时出现问题settings.INSTALLED_APPS:

for app in settings.INSTALLED_APPS:
    try:
        mod = import_module(app)
    except ImportError as e:
        raise ImproperlyConfigured('ImportError %s: %s' % (app, e.args[0]))
    template_dir = os.path.join(os.path.dirname(mod.__file__), 'templates')

似乎更容易确定哪个模块导致了问题.在Django中调试此类问题的一种常见方法是使用Werkzeug,您可以在其中使用浏览器内调试器快速查看发生错误时变量的值.

现在,我强烈怀疑导致此问题的模块是piston[ 相关线程 ].您可以通过__init__.py在任何目录中创建文件来修复它piston.

Answer 2

尝试使用应用程序时,如果它不是Python包,则会出现此问题,因此请确保您的应用程序__init__.py在其根目录中包含文件.
