Property or method "defaultProps" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components,

这个错误通常发生在使用Vue单文件组件时,因为Vue单文件组件中可以同时包含template、script和style标签,而这三个标签中的代码是分别独立编译的。因此,在模板中引用的数据或方法必须在Vue实例的data或methods选项中进行定义。
根据错误提示,你使用了一个名为"defaultProps"的属性,但是它没有被定义或者没有被正确定义。解决这个问题,你需要在Vue实例的data选项中定义"defaultProps"属性。例如:
```
<template>
<div>{{defaultProps}}</div>
</template>
<script>
export default {
data() {
return {
defaultProps: '默认属性'
}
}
}
</script>
```
如果你仍然无法解决这个问题,可能是其他原因导致的。你可以仔细检查模板中的代码,确保所有的数据和方法都被正确定义和引用。另外,你可以查看浏览器控制台的错误信息,以获取更多的错误提示。

Property or method "index" is not defined on the instance but referenced during render. Make sure that this property is reactive
This error usually occurs when you are referencing a property or method in your Vue component's template that is not defined in the component's instance. To fix this, make sure that the property or method you are using in the template is declared and defined in the component's `data`, `computed`, or `methods` sections.
If the property is supposed to be reactive, you can define it in the `data` section of your component. For example:
```javascript
data() {
return {
index: 0
};
}
```
If the property is a computed property, you can define it in the `computed` section. For example:
```javascript
computed: {
index() {
// compute and return the index value
}
}
```
If the property is a method, define it in the `methods` section. For example:
```javascript
methods: {
index() {
// perform some calculations or actions and return the index value
}
}
```
Make sure to check for typos or incorrect naming when referencing the property or method in your template.
Property or method "articleInfos" is not defined on the instance but referenced during render. Make sure that this property is reactive,
这个错误是由于在渲染期间引用了一个名为"articleInfos"的属性或方法,但是在实例中没有定义它。要解决这个问题,你需要确保在Vue实例的data选项中定义了"articleInfos"属性,并且该属性是响应式的。这样Vue才能正确地检测到该属性的变化并进行重新渲染。如果你正在使用vuex,你还需要确保在store.js中正确地定义了"articleInfos"的状态和相关的mutations或actions。 如果你正在使用类组件,你还需要在类中初始化该属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
