我正在做"Django 3 by example"中的教程"Blog"，但我遇到了错误。我做错了什么？
错误：找不到页面(404(请求方法：GET请求URL:http://127.0.0.1:8000/blog/amd alsp TemplateDoesNotExist，位于/blog/。Django使用mysite.urls中定义的URLconf尝试了以下URL模式，顺序如下：admin/当前URL blog/与其中任何一个都不匹配。

找不到模板的第一个错误是因为settings.py文件中没有指定其路径
第二个是因为您没有在mysite/urls.py中指定/路径
如果你想要更多的解释，请随时询问。
