Module not found: Error: Can't resolve 'React' in '/home/capaj/project/node_modules/react-visibility-sensor/dist'

I have webpack 4 and react-visibility-sensor 5.0.2
and when I import like this:
`import VisibilitySensor from "react-visibility-sensor"`
I get
```
ERROR in ../node_modules/react-visibility-sensor/dist/visibility-sensor.js

```
when I change to import the source file:
`import VisibilitySensor from 'react-visibility-sensor/visibility-sensor'`

it works great.

The webpack thingy seems to think I the app run in an UMD loader and hence it tries to load deps from globals.
