undefined is not an object (evaluating 'regeneratorRuntime.mark')- React Native - reactjs

Question

react-native: 0.49.5
react-native-cli: 2.0.1
node: 8.6.0
Have this error while running my application. It just started to randomly have problems after I started using proptypes in my react native application (do not think that is the problem).
I tried to comment out my store and proptypes to see if that affects anything and I still get the same error.
Note: I tried removing the caret symbol from my package.json, then removing node_modules, then finally installing again with no effect.
UDPATE:
I did some more digging and got the error to say this :
Error: ENOENT: no such file or directory, open '/Users/christian/Desktop/React-Native/roam/node_modules/react-native/node_modules/regenerator-runtime/package.json'
UPDATE:
I removed my node_modules and reinstalled them and now I am getting a similar error but with a different package.
Error: ENOENT: no such file or directory, open '/Users/christian/Desktop/React-Native/roam/node_modules/simple-swizzle/node_modules/is-arrayish/package.json'

Answer 1

The problem is that one of your library is still importing the
prop-types
from react-native bundle.
You have to correct that.

Answer 2

I was able to get it to work by downgrading React to 16.0.0-beta.5
