Hej！这里的许多线程都有相同的标题，但没有一个解决了我的问题。我有一个Django站点可以访问/admin（但它看起来很丑）。但是在/上出现了以下错误页面（DEBUG = True in settings.py）：

TemplateDoesNotExist at /

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，我也尝试了chmod o+r index.html，但没有成功。
python iecl_dev/manage.py runserver 0.0.0.0:0的输出为

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.

所以这里一切正常
令我困惑的是：当运行 .py文件时，.pyc文件会自动创建，对吗？在python iecl_dev/manage.py runserver 0.0.0.0:0之后，会创建一个文件/home/django/django/iecl_dev/settings.pyc。但是当我在Web浏览器中加载页面时，它并没有创建。这是否意味着settings.py从未加载过？Django怎么能说，一个存在的文件不存在呢？
编辑¹：
我的settings.py看起来如下：

好了。现在我解决了这个问题。解决方案是不同事情的集合。其中一个问题是缺少权限。执行Django的用户无法列出templates/目录的内容。chmod o+x templates/完成了这项工作。然后在www.example.com中有一些设置settings.py，将查找模板的位置从templates/iecl_dev/更改为iecl_dev/templates/。我在我的Web浏览器的错误消息中看到了这个错误的路径。但是简单地将settings.py恢复到旧版本是不够的。一些服务需要重新启动。我只是重新启动机器，一切都很好。奇迹般地，/admin/页面现在看起来也很好。
非常感谢您的所有提示。

从您所展示的内容来看，我认为您的项目布局可能存在问题。
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

正如你所看到的，项目中的每个应用都可以有自己的templates目录。yourproject有点特殊，因为它还存储了独特的文件，如settings.py和wsgi.py。但是，你可以考虑将其作为一个应用使用。
现在，如果您想使用存储在yourproject/templates中的模板，则必须将yourproject添加到INSTALLED_APPS设置中。
这有帮助吗？如果没有，你能用你的项目布局编辑你的原始文章吗？

我花了很多时间试图找出我的'templates'目录的错误，并发现：
您可能忘记在settings.py的以下段中添加TEMPLATE_DIR：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

所以它应该有'DIRS': [TEMPLATE_DIR,],而不是'DIRS': [],

原因可能是django试图在www.example.com文件所在的目录中查找templates目录setting.py，而实际上templates目录在父目录中。settings.py

SETTINGS_PATH = os.path.dirname(__file__)
PROJECT PATH = os.path.join(SETTINGS_PATH, os.pardir)
PROJECT_PATH = os.path.abspath(PROJECT_PATH)
TEMPLATES_PATH = os.path.join(PROJECT_PATH, "templates")

TEMPLATE_DIRS = (
    TEMPLATES_PATH,
)

错误通常是由于模板目录配置不正确

我知道这是晚了，但这里提到的解决方案并没有为我工作.所以这里是什么工程：
1.在settings.py文件中，将appConfig添加到已安装的应用程序中。
INSTALLED_APPS = [ '...', 'AppName.apps.AppNameConfig', ]
1.创建一个模板目录appName/templates/appName .（其中appName是应用程序的名称）。
1.当你调用render函数时，你可以传递templates.name.html。像这样：
return render(request, 'templates/blog.html')

对于任何人回来后，这似乎你可以简单地做

from django.shortcuts import render

# Create your views here.
def index(request):
    # I guess for some reason you don't need to tell that it is in the templates folder anymore
    return render(request, 'home.html')

你可以只把应用程序的名称放在settings.py已安装的应用程序中（“核心”在这里）

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'core'
]
