这个错误通常是由于在Vue组件中使用了未定义的变量或属性而引起的。在这种情况下,'status'属性未被正确定义,因此无法设置。要解决此问题,您可以采取以下步骤:
1.检查代码中是否存在任何拼写错误或语法错误,特别是在定义变量和属性时。
2.确保在Vue组件中正确定义了'status'属性。您可以在组件的data选项中定义它,如下所示:
```javascript
export default {
data() {
return {
status: 'pending'
}
},
methods: {
handleProgress() {
// do something with this.status
}
}
}
```
3.如果您正在使用第三方库或插件,请确保它们已正确安装并按照文档进行使用。

Uncaught TypeError: Cannot set properties of undefined (setting 'id')
This error occurs when you try to set a property (in this case, 'id') on an object or variable that is undefined.
For example, if you have an object called 'person' and you try to set the 'id' property on it before initializing it, you will get this error:
```
let person;
person.id = 123; // Uncaught TypeError: Cannot set properties of undefined (setting 'id')
```
To fix this error, make sure that the object or variable you are trying to set the property on is defined and initialized before setting any properties on it.
```
let person = {};
person.id = 123; // no error
```
