After the react-navigation RN 0.6 navigation error null is not an object (evaluating '_RNGestureHandlerModule.default.Direction')

Long useless RN or a very early version of time before use, and now has changed a lot, I feel a lot of maturity than before re-look. 
First adjust the next navigation reference address: https://reactnavigation.org/docs/en/getting-started.html
 the Yarn the Add-REACT Navigation 
the Yarn the Add-REACT-Native-Gesture Handler REACT-Native-reanimated 

reported the wrong search for a long, finally
