You probably need to build the client:

$ npm install
$ npm run webpack

[zpget]

Had the same issue (nothing at url) - the npm install commands fixed it, doing a PR to update the readme. Thanks for the suggested fix @zpget

I had the same issue. Rinning python run.py resulted in the "Sorry, Nothing at this URL." error. Installing

$ npm install
$ npm run webpack

fixed it.

@SinOverCos That looks like a separate error that the project isn't building properly for you (although strangely it looks like it's an error in the webpack code), I'd open a separate issue about that

okay, I copy the app/public from https://github.com/Netflix/flamescope/tree/v0.2.0 to the master branch, it works. Consider it as a temporary workaround.
