我正在尝试将 url 转到用户个人资料的页面。我(?P<pk>\d+)在 url 中使用它来执行此操作，但是出现错误。此外，如果我删除在 base.html 中链接它的那个问题就会消失。但是后来我在 nabber 中没有链接...
错误：
NoReverseMatch at /
Reverse for 'user_profile' with no arguments not found. 1 pattern(s) tried: ['user/(?P<pk>\\d+)/$']
In template /Users/garrettlove/Desktop/evverest/templates/base.html, error at line 23

它将上面代码中的第 23 行高亮显示为错误。
这是我的代码：
