The error of van swipe in the rotation chart: cannot read a properties of null (reading width)

In the use of vant When doing mobile terminal projects , When using the carousel map plug-in , stay data The above error will be thrown in the simulation data ：
The solution given on the official website ：
1. Use v-if Instead of v-show, use v-if To determine loading
2、 Use delayed re rendering .
watch: {
list(val) {
var _this = this;
setTimeout(() => {
_this.$refs.swipe.resize();
}, 500);
},
},
Tried two schemes ： If the data is fixed directly in data in , It doesn't work
Unless stay data It is declared in that the rendered rotation list is empty , Assign value again when the data request comes , No problem
