Cannot read property 'string' of undefined | React.PropTypes | LayoutPropTypes.js

[gyetvan-andras]

After deleting and reinstalling my node_modules folder, I'm facing an issue that I don't understand in LayoutPropTypes.js file.

In node_modules/react-native/Libraries/StyleSheet/LayoutPropTypes.js
The following variable is undefined : var ReactPropTypes = require('React').PropTypes;

react-native: 0.45.1
react: 16.0.0-alpha.12

Hey @hramos , don't close this issue giving an advice to search for solution on StackOverflow. It is a critical issue. My whole development is down because of this. And of course, first I tried to look an answer on StackOverflow, the only answer is to use prop-types package, but HOW in RN source?!

Did you try Reactiflux? If you really think this belongs in the issue tracker, at least make an effort to fill out the template. Thanks!
