Unable to instantiate prefab. Prefab may be broken.(Unity2018.2.2报错)

将Prefab资源导入Unity的时候,一切正常,当拖拽的时候,突然给了一个警告

Unable to instantiate prefab. Prefab may be broken.

然后就一直找论坛解决问题..然后 https://answers.unity.com/questions/1562622/unable-to-instantiate-prefab-prefab-may-be-broken-1.html

有为大佬给出解决办法:

 the simplest solution for that is (Right click on the prefab and then hit Reimport)

意思就是..右键你所选中的预制体,重新导入一下.. 右键 -> Reimport

这个时候就好了...
