phpstorm/webstorm/idea 出现一只刷新缓存Updating Index

其实解决方案特别简单。

fild->Invalidate Caches / Restart.

确定

1. Open IntelliJ IDEA
2. Select the File menu
3. Select the Invalidate Caches / Restart... menu.
   Once selected you get a pop-up with a bunch of options.
4. Select Invalidate and Restart
   and before doing that make sure you saved all your changes else it might delete some unsaved changes.
