Error in onLoad hook: "TypeError: Cannot read properties of undefined (reading 'open')"

出现"Error in onLoad hook: "TypeError: Cannot read properties of undefined (reading 'open')"的错误通常是因为在加载组件时，尝试读取一个未定义（undefined）的属性，具体是'open'。根据引用的介绍，这个错误可能是由于在调用组件时，尚未正确引入echarts库所致。

要解决这个问题，可以按照引用中的方法进行操作。首先，在main.js文件中全局引入echarts库，并将其挂载到Vue的原型上，以便在组件中可以直接访问到echarts对象。具体的代码如下：

// 引入echarts
import * as echarts from 'echarts';

// 将echarts挂载到Vue的原型上
Vue.prototype.$echarts = echarts;

这样，就可以在组件中通过this.$echarts来访问echarts对象，避免了读取未定义属性的错误。然后，确保在组件中正确引入echarts：

// 在组件中引入echarts
import * as echarts from 'echarts';

通过以上操作，应该能够解决"Error in onLoad hook: "TypeError: Cannot read properties of undefined (reading 'open')"的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
