模板不存在于 /

嘿嘿！这里的许多线程都有相同的标题，但没有一个能解决我的问题。我有一个 Django 站点，可以访问 /admin （但它看起来很丑）。但在 / 上出现以下错误页面（DEBUG = True in settings.py):

Template-loader postmortem

Django tried loading these templates, in this order:

    Using loader django.template.loaders.filesystem.Loader:  
        /home/django/django/templates/iecl_dev/index.html (File does not exist)  
    Using loader django.template.loaders.app_directories.Loader:  
        /usr/lib/python2.7/dist-packages/django/contrib/auth/templates/index.html (File does not exist)  
        /usr/lib/python2.7/dist-packages/django/contrib/admin/templates/index.html (File does not exist)

事实上，文件 /home/django/django/templates/iecl_dev/index.html 确实存在，我也尝试过chmod o+r index.html没有成功。

的输出python iecl_dev/manage.py runserver 0.0.0.0:0 is

Validating models...

0 errors found  
Django version 1.4.5, using settings 'iecl_dev.settings'  
Development server is running at http://0.0.0.0:0/  
Quit the server with CONTROL-C.

所以这里一切看起来都很好。

让我困惑的是：运行 *.py 文件时会自动创建 *.pyc 文件，对吧？后python iecl_dev/manage.py runserver 0.0.0.0:0有一个文件/home/django/django/iecl_dev/settings.pyc创建的。但当我在网络浏览器中加载页面时，它并未创建。这是否意味着 settings.py 从未加载？ Django 怎么能说一个存在的文件就不存在呢？

Edit¹:
我的 settings.py 如下所示：

Edit³:
好的。现在这对我来说已经解决了。解决方案是不同事物的组合。问题之一是权利缺失。执行 Django 的用户无法列出 templates/ 目录的内容。chmod o+x templates/完成了工作。然后，settings.py 中进行了一些设置，将查找模板的位置从 templates/iecl_dev/ 更改为 iecl_dev/templates/。我在网络浏览器的错误消息中看到了这个错误的路径。但仅仅将 settings.py 恢复到旧版本是不够的。某些服务需要重新启动。我只是重新启动机器，一切都很好。奇迹般的是，/admin/ 页面现在看起来也不错。

非常感谢您的所有提示。

从你所展示的情况来看，我认为你的项目布局可能有问题。

通常，设置如下：

├── manage.py
├── yourproject
│   ├── __init__.py
│   ├── settings.py
│   ├── templates
│   ├── urls.py
│   ├── wsgi.py
│   └── wsgi.pyc
├── yourfirstapp
│   ├── __init__.py
│   ├── admin.py
│   ├── models.py
│   ├── templates
│   ├── tests.py
│   ├── urls.py
│   └── views.py
├── yoursecondapp
    ├── __init__.py
    ├── admin.py
    ├── models.py
    ├── templates
    ├── tests.py
    ├── urls.py
    └── views.py

如您所见，项目中的每个应用程序都可以拥有自己的templates目录。yourproject有点特殊，因为它还存储独特的文件，例如settings.pyand wsgi.py。但是，您可以考虑将其用作应用程序。

现在，如果您想使用存储在中的模板yourproject/templates，你必须添加yourproject给你的INSTALLED_APPS设置。

有帮助吗？如果没有，您可以用您的项目布局编辑您的原始帖子吗？
