重现步骤 用微信开发者工具导入本项目的dist/weapp ，将显示测试页面： 页面源码为本项目src/pages/test-field/index.vue, 点击测试按钮1，微信开发者工具控制台显示错误信息，经跟踪是执行到 vant/es/field/Field.mjs 的 watch(() => props.modelValue, () => { updateValue(getModelValue()); resetValidation(); validateWithTrigger("onChange"); nextTick(adjustTextareaSize); }); 时报错的。经试验，如果同时把响应式变量绑定给一个taro原生field，则vant field也不会报错，效果见测试按钮2
