vant introduces components as documents:
import { Button} from "vant";
Vue.use(Button)can be used normally, but the introduction of Field, in the same method will prompt an error,
in addition, when using the Dialog component, it is written in the official document:
`
after the introduction of the Dialog component, the $dialog method will be automatically mounted on the prototype of Vue, and this method can be called directly within all components
`
import Vant from "vant";
import "vant/lib/vant-css/index.css";
Vue.use(Vant); but when using the this.$dialog.alert ({}) method, it prompts alert alert to print this.$alert as undefined for undefined,.
what is the reason?
Supplementary Code:
