【问题描述】：
我正在使用 django 1.10 和 python 3.6 创建一个网站。 我的网络应用程序称为“配置文件”，项目称为“firstsite”。我使用了来自 bootstrap 的模板，该模板保存为“base.html”。我的 webapp 中有两个页面使用模板“home.html”和“about.html”。导航栏是另一个名为“navbar.html”的 html 文件。我正在尝试在导航栏中链接“主页”和“关于”。链接后，当我运行服务器并打开“http://127.0.0.1:8000/”时，出现“NoReverseMatch at/”错误。

正如您在 navbar.html 中看到的，{% url 'home' %} 应该可以工作，但我收到此错误：
如果我在 navbar.html 中删除 {% url 'home' %} 并放置 #，则网站可以正常运行，没有任何错误。
