为什么Django 4.0中存在TemplateDoesNotExist错误

Question

我是Django的新手，我已经为这个TemplateDoesNotExist错误挣扎了一段时间。我查看了许多其他有这些问题的用户，但似乎没有一个提出的解决方案对我有效

Django找不到我的blog/base.html文件，并声称它在'/home/agile/djang_project/blog/templates/blog/base.html'中查找，但当我检查我的ubuntu时，它说目录存在，好吗？

当我在本地主机上运行时，该网站运行良好，但当我使用ubuntu和Linode时，就会遇到这个问题。

Django错误的图像

存在但Django找不到的路径的图像？

再次，我尝试了许多"解决方案"，通过添加到模板DIRS之类的东西，但老实说，没有一个奏效。我只是不知道出了什么问题/该怎么办。如果有任何帮助，我将不胜感激。

更新：

我能够修复它；blog/base.html"；而不是"；blog/base.html">

这也是我的settings.py文件：

Answer 1

在settings.py中使用这个模板

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'blog')],
'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',
],
},
},
]
