TypeError: Cannot read property 'styleKeeperContext' of undefined

I read that Radium used the *old* context API? Does that mean Radium doesn't work anymore? What is another alternative?
**This is not the full script**

```javascript
import Radium from 'radium'

const style = {
      ':hover':{
        backgroundColor: 'lightgreen',
        color:'black'
      }
}
export default Radium(App);
