React报错 object doesn't support property or method 'locale'解决方案

报错主要内容如下：

object doesn't support property or method 'locale'.

由下面的原因导致：

Invalid prop `value` of type `string` supplied to `Calendar`, expected `object`.

Invalid prop `value` supplied to `Picker`.

Failed prop type: Invalid prop `selectedValue` of type `string` supplied to `Calendar`, expected `object`

 

 

 

解决方法：

Datapicker组件不能初始赋值为空值：“”

而应该赋值 null
