关于Django错误消息TemplateDoesNotExist位于/

我正在尝试为Django的博客做一个应用程序，但是没有显示首页（

post_list.html

）。 将显示以下错误消息

 TemplateDoesNotExist at /
 blogapp3/post_list.html
 Request Method:    GET
 Request URL:   http://127.0.0.1:8000/
 Django Version:    1.11.4
 Exception Type:    TemplateDoesNotExist
 Exception Value:   
 blogapp3/post_list.html
 Exception Location:    F:\01_pro\kaso3\lib\site-packages\django\template\loader.py in select_template, line 53
 Python Executable: F:\01_pro\kaso3\Scripts\python.exe
 Python Version:    3.6.2

 Template-loader postmortem

 Django tried loading these templates, in this order:

 Using engine django:
 django.template.loaders.filesystem.Loader: F:\01_pro\blogpro3\blogapp3\templates\blog\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\kaso3\lib\site-packages\django\contrib\admin\templates\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\kaso3\lib\site-packages\django\contrib\auth\templates\blogapp3\post_list.html (Source does not exist)
django.template.loaders.app_directories.Loader: F:\01_pro\blogpro3\blogapp3\templates\blogapp3\post_list.html (Source does not exist)

我曾被指出，其他网站的文件结构是错误的，但我认为这个文件似乎并不奇怪。文件结构如下

我要注意的是错误消息的下面一部分

Template-loader postmortem

 Django tried loading these templates, in this order:

 Using engine django:
 django.template.loaders.filesystem.Loader: F:\01_pro\blogpro3\blogapp3\templates\blog\blogapp3\post_list.html (Source does not exist)

上面的路径对于下面的路径应该是正确的

F:\01\u pro\blogpro3\blogapp3\templates\blog\post\u list.html

然而，我不知道如何修复上述路径。

---

如果你告诉我如何解决这个问题，我很高兴。

你的文件结构准确地证实了错误所说的：没有名为“blogapp3”的模板目录，因此没有名为“blogapp3/post_list.html”的模板

---

您应该将模板移动到“blogapp3”目录中。

对不起，我已经在blogapp3中找到了模板文件夹。它也显示在上面的树结构中。但是在这个目录中你有模板->博客。应该是blogapp3。正如您所指出的，我将目录名从“blog”更改为“blogapp3”，因此我能够显示post_列表，html。非常感谢你！结论：当我改变如下路径时，我可以正确显示post_list.html。错误的F:\01\U pro\blogpro3\blogapp3\templates\blog正确的F:\01\U pro\blogpro3\blogapp3\templates\blogapp3非常感谢！
