配置不正确：导入模块时出错django.middleware.cache.FetchFromCacheMiddlewaredjango.middleware.clickjacking：

Question

我正在尝试第一次在openshift上部署应用程序。代码使用的是Python 2.7，Django 1.6，MySQL Server 5.6。 我在C：\ Users \ welcome \ resume \ wsgi \ openshift路径上获得了克隆的默认代码。

现在，根据https://www.openshift.com/developers/deploying-and-building-applications链接，首先我们需要在本地运行我们的代码。之后我们可以将代码推送到openshift。

根据我的理解，我们需要将我们的代码文件添加到此文件夹，并根据要求在settings.py，setup.py等中进行适当的更改。

注意：我没有对wsgi.py文件进行任何更改

尝试在本地运行代码时，我遇到错误：

请告诉我哪里出错了。此外，如果可能的话，还可以指导何处进行更改以及在哪些文件中以及在何处准确复制代码。

你在“django.middleware.cache.FetchFromCacheMiddleware”之后的设置中忘记了一个“，”

至于要复制的内容和要修改的文件，django文档几乎在框架的每个方面都非常精细和详细： https://docs.djangoproject.com/en/1.6/

编辑后：

此：

 'django.middleware.cache.FetchFromCacheMiddlewaredjango.middleware.clickjacking',

应该是：

  'django.middleware.cache.FetchFromCacheMiddleware',
  'django.middleware.clickjacking',

在您的MIDDLEWARE设置中
