cannot read properties of null reading router
时间: 2024-04-16 19:21:42 浏览: 20
"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。

cannot read properties of undefined reading matched
这个错误"Cannot read properties of undefined (reading 'matched')"通常是由于访问了一个未定义的属性而引起的。根据引用,这个错误可能是在访问一个未定义的'matched'属性时出现的。
根据引用,解决这个问题的方法是检查导入的router实例对象的属性名是否正确。确保在实例化对象中的属性名和值名一致。
另外,根据引用,一种解决方法是将导入的Router改成小写的router,并且将所有相关的Router都改成小写。
综上所述,如果你遇到了"cannot read properties of undefined reading matched"错误,你可以检查一下导入的对象属性名是否正确,并将相关的属性名改成小写,以解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
