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

"Property or method 'getResultAlone' is not defined on the instance but referenced during render."这个错误提示意味着在渲染期间引用了名为"getResultAlone"的属性或方法，但是该属性或方法在实例中未被定义。这可能是由于未正确导入或定义组件或函数导致的。您可以检查代码中是否正确导入了相关组件或函数，并确保在组件或函数中正确定义了"getResultAlone"属性或方法。

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.

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

当出现Property or method "fileList" is not defined on the instance but referenced during render的错误时，这意味着在Vue组件实例中没有定义名为fileList的属性或方法，但在渲染过程中被引用了。

要解决这个问题，你可以采取以下步骤：

1. 确保在Vue组件实例中定义了fileList属性或方法。你可以在data属性中初始化fileList，或者在methods属性中定义一个名为fileList的方法。

2. 检查是否正确引用了fileList属性或方法。请确保在模板中正确地使用了指令或插值表达式来引用fileList。

3. 如果在组件内部的计算属性或侦听器中使用了fileList，请确保在组件实例中定义了该计算属性或侦听器。

4. 检查是否存在拼写错误或语法错误。请仔细检查你在组件中定义和引用fileList属性或方法的拼写和语法。

通过以上步骤，你应该能够解决Property or method "fileList" is not defined on the instance but referenced during render的问题。
