javascript - VueJs 路由器链接元素出错

Question

每次我在我的 app.blade.php 页面导航栏中单击我的 vuejs router-link 元素之一时，我最终会在我的控制台上收到一个错误，如下所示

 [Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "to"

 found in

 ---> <RouterLink>
   <Root>

下面的代码显示了我如何在导航栏中实现路由器链接。

<ul class="navbar-nav ml-auto">
                    <!-- Authentication Links -->
                    @guest
                        <li class="nav-item">
                            <a class="nav-link" href="{{ route('login') }}">{{ __('Login') }}</a>
                        </li>
                        <li class="nav-item">
                            <a class="nav-link" href="{{ route('register') }}">{{ __('Register') }}</a>
                        </li>
                    @else
                        <li class="nav-item"  id="navbarDropdown" class="nav-link" role="button" aria-haspopup="true" aria-expanded="false" style="padding: 15px; ">

                               <router-link style="color:black;" :to="{ name: 'home' }">Menu<i class="fa fa-home" style="margin-left:8px;"></i></router-link>
                        </li>

                        <li class="nav-item"  id="navbarDropdown" class="nav-link" role="button" aria-haspopup="true" aria-expanded="false" style="padding: 15px;">

                               <router-link style="color:black;" :to="{ name: 'orders' }">Orders <i class="fa fa-coffee" style="margin-left:8px;"></i></router-link>
                        </li>



                        <li class="nav-item"  id="navbarDropdown" class="nav-link" role="button" aria-haspopup="true" aria-expanded="false" style="padding: 15px;">

                               <router-link style="color:black;" :to="{ name: 'cart' }">Cart <i class="fa fa-shopping-cart" style="margin-left:8px;"></i></router-link>
                        </li>

有人可以解释为什么我会收到此错误吗？

您正在尝试更改 vue 组件内的 props 元素。为此目的使用data。
