Property or method "isviplist" is not defined on the instance but referenced

这个错误提示意味着在代码中引用了名为"isviplist"的属性或方法，但是该属性或方法在实例中并未定义。这通常是由于以下几种情况导致的：

1. 拼写错误：请检查代码中对"isviplist"的拼写是否正确。确保大小写和命名规范都正确。

2. 作用域问题：如果"isviplist"是一个类的属性或方法，确保它在当前作用域内可见。如果它是另一个对象的属性或方法，请确保该对象已经正确实例化。

3. 缺少定义：如果"isviplist"确实是你自己定义的属性或方法，那么请确保你在代码中正确地定义了它。检查是否存在拼写错误、缺少必要的参数或者忘记添加修饰符等问题。

如果你能提供更多的上下文信息，我可以给出更具体的解决方案。

Property or method "scope" is not defined on the instance but referenced during render.

The error message "Property or method 'scope' is not defined on the instance but referenced during render" indicates that the property or method named "scope" is being used in the template during rendering, but it is not defined in the component instance.

To resolve this issue, you'll need to make sure that the "scope" property or method is properly defined in the component. Here are a few steps you can take to troubleshoot and fix the problem:

1. Check if "scope" is declared in the component's data object. If it's not there, you can add it like this:

data() {
  return {
    scope: // initial value,
    // other data properties
 }
},

2. If "scope" is not a data property, make sure it is defined as a computed property or a method in the component:

computed: {
  scope() {
    // compute and return the value of 'scope'
  },
},

or

methods: {
  scope() {
    // define the logic for 'scope' and return its value
  },
},

3. If you are using a third-party library or plugin that provides the "scope" functionality, make sure you have properly imported and initialized it in your component.

By following these steps, you should be able to resolve the "Property or method 'scope' is not defined on the instance but referenced during render" error.
