Unable to run usage.py : No such file for bundle.js #62

Hi,

I am playing around this beautiful work of dash table and when I try to access the web produced by the example code: usage.py, I have the following error:

I had installed : dash, dash-renderer, dash-html-components, dash-core-components. What package is missing to have the result display? It seems to be a missing Javascript?

Thank you

That JavaScript file comes from dash_table_experiments but I would have thought for your app to be calling it from the front end, you must have already installed it. Perhaps double check that you have it installed and at the latest version: pip install -U dash_table_experiments.

If it's still not working, you could also try again using the CDN-hosted versions of the JavaScript assets by removing the line app.scripts.config.serve_locally = True (which it looks like you've got set).

Hi Ned,

Thanks for the reply. After comment out the line app.scripts.config.serve_locally = True in the sample code usage.py , it works on localhost web!

Thank you.
