参考21905
// ElemeFE/element#21905
// 解决 Instead, use a data or computed property based on the prop's value. Prop being mutated: "placement"
main.js 添加如下即可解决

function RepairProps(cmp) {
  (cmp.mixins || []).forEach(mixin => {
    if (mixin.props && mixin.props.placement) {
      const defaultValue = mixin.props.placement.default
      mixin.data = new Proxy(mixin.data, {
        apply(target, thisArg, argArray) {
          const res = Reflect.apply(target, thisArg, argArray)
          return {
            ...(res || {}),
            placement: defaultValue
          }
        }
      })
      delete mixin.props.placement
    }
    if (mixin.mixins && mixin.mixins.length > 0) {
      RepairProps(mixin)
    }
  })
}

RepairProps(Element.DatePicker)
RepairProps(Element.TimePicker)
RepairProps(Element.TimeSelect)
