## 二、报错说明 ##

错误的原因是项目中引入了vue-class-component，但是在项目的依赖列表中，却没有找到它，因此会报如上的错误。

### 2.1 vue-class-component介绍 ###

vue-class-component是一个用于类式Vue组件的TypeScript装饰器。  
它允许您将Vue组件定义为类，这可以使您的代码更有组织性和易于阅读。  
它还提供了其他装饰器，用于定义计算属性、观察者和事件处理程序。

[官方文档][Link 1]

### 2.2 使用vue-class-component ###

要使用vue-class-component，您首先需要通过npm安装它：

npm install vue-class-component

安装后，您可以在Vue组件文件中导入它，并使用@Component装饰器将组件定义为类：

import {
         Component, Vue } from 'vue-class-component';
    
    @Component
    export default class MyComponent extends Vue {
        
      // 组件逻辑在这里
    }

然后，您可以将组件的数据、方法和生命周期钩子定义为类属性和方法：

@Component
    export default class MyComponent extends Vue {
        
      // 数据
      message: string = 'Hello, world!';
    
      // 方法
      onClick(): void {
        
        console.log('Button clicked!');
      }
    
      // 生命周期钩子
      mounted(): void {
        
        console.log('Component mounted!');
      }
    }

## 三、报错解决 ##

引入vue-class-component即可，并且重新执行一下Jenkins的构建，即重新build一波试试，问题解决！
