Fetch API cannot load webpack-internal:///./src/atoms/div/Div.js. URL scheme "webpack-internal" is not supported.

Hi
I've just cloned and run atomize then got this issue
```
Fetch API cannot load webpack-internal:///./src/atoms/div/Div.js. URL scheme "webpack-internal" is not supported.
Debug worker error TypeError: Failed to fetch
    at worker.js:1
    at d (worker.js:1)
    at worker.js:1
    at add_mapped_class (worker.js:1)
    at self.onmessage (worker.js:1)
```
What do I miss?
