ReferenceError: ref is not defined

This error occurs when you try to use a variable that has not been defined in your code.
To fix this error, you need to define the variable before using it. Make sure that you have declared the variable using the var, let, or const keyword.
For example, if you see this error in the following code:
```
console.log(ref);
```
You should define the `ref` variable before using it:
```
const ref = "some value";
console.log(ref);
```

vant报错Uncaught ReferenceError: ref is not defined通常是由于使用了vant的组件,但是没有正确引入所需的依赖库或者版本不匹配导致的。可以检查以下几个方面:
1.检查vant的版本是否与Vue版本匹配,可以查看vant官方文档来确认版本号是否正确。
2.检查是否正确引入vant的依赖库,比如vue-router、vuex等依赖库。
3.检查是否正确引入vant的组件,可以检查组件的命名是否正确,组件是否正确导出等。
