unity2019.1.02f导入资源包运行时遇到error CS0104: 'MinAttribute' is an ambiguous reference between 报错

导入资源商店中下载的资报错：PostProcessing\Editor\PropertyDrawers\MinDrawer.cs(6,34):error CS0104: 'MinAttribute' is an ambiguous reference between 'UnityEngine.PostProcessing.MinAttribute' and 'UnityEngine.MinAttribute'。

解决方法：将MinDrawer.cs中所有的MinAttribute替换为UnityEngine.PostProcessing.MinAttribute。
