Property or method "v" 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, by initializing the property

这个错误通常是因为你在模板中引用了一个在组件实例中未定义的属性或方法 "v"。你需要确保在组件实例中定义了该属性或方法,并且该属性或方法是响应式的。
如果你使用了 Vue.js,你可以将该属性或方法添加到组件的 data 选项中,以确保它是响应式的。如果你使用了 class-based components,则需要在组件的 constructor 中初始化该属性。
例如,如果你的组件模板中引用了一个名为 "v" 的属性,你可以像这样在组件实例中定义它:
```
<template>
<div>{{ v }}</div>
</template>
<script>
export default {
data() {
return {
v: 'Hello world'
}
}
}
</script>
```
如果你仍然遇到问题,请检查模板中是否存在其他错误,并确保你正确引入了组件。

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>
