This error usually occurs when trying to access the `$router` property on a null object. The `$router` property is typically available in Vue.js components that are within the Vue Router's scope.
To fix this issue, make sure that you are trying to access the `$router` property within a Vue component that is properly registered with the Vue Router. Additionally, ensure that the component is rendered within the scope of the router-view component.
If you still encounter this error, please provide more information about your code and where you are trying to access the `$router` property so I can assist you further.

cannot read properties of null reading router
"Cannot read properties of null"是JavaScript中常见的错误消息,它表示在尝试读取一个null或undefined值的属性时发生了错误。在这种情况下,你可能正在尝试读取一个名为"router"的属性,但该属性的值为null。
这个错误通常发生在以下几种情况下:
1. 你可能没有正确地初始化或定义"router"变量。请确保在使用该变量之前对其进行初始化。
2. "router"可能是一个异步操作的结果,而你在它完成之前就尝试读取它的属性。在这种情况下,你需要等待异步操作完成后再访问属性。
3. "router"可能是一个对象的属性,而该对象本身为null。在这种情况下,你需要确保对象不为null后再访问属性。
为了解决这个问题,你可以按照以下步骤进行排查:
1. 检查代码中是否正确初始化了"router"变量。
2. 确保在访问"router"属性之前,它已经被正确地赋值。
3. 检查相关的异步操作是否已经完成,再尝试访问"router"属性。
[Vue warn]: Error in v-on handler: "TypeError: Cannot read properties of null (reading '$router')"
这个报错是因为在点击事件处理函数中使用了this.$router,但是this.$router为null导致的。根据引用中提供的解决方案,可以尝试使用this.$router.replace(this.path)来跳转页面。但是由于可能会抛出错误,所以使用.catch(err => err)来捕获错误。另外,引用中提到,如果你使用的是脚手架2,删除.catch(err => err)反而会报错,而脚手架3可以删除这部分代码。因此,你可以尝试删除.catch(err => err)这一行代码来解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
