I'm sorry but i don't see any issue here, read the tutorial if your problem is how to load demo data http://airbnb.io/caravel/installation.html#caravel-installation-and-initialization

@xrmx
when i install the caravel, everything is ok. but now i want to build it by source code, i follow those steps:

• npm install
• npm run prod
• python setup.py install

no errors has been found in those steps, then i run it, but the dashboards and slices has nothing to show. there was a problem in chrome's console:

web_worker.js?e7d2:5Uncaught TypeError: Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.(…)

[xrmx]

@ujhujuh And how i was supposed to know that if you don't mention the actual error in your bug report?

alias: { webworkify: 'webworkify-webpack',
'mapbox-gl/js/geo/transform':APP_DIR + '/node_modules/mapbox-gl/js/geo/transform',
'mapbox-gl':'mapbox-gl/dist/mapbox-gl.js')

edit inside webpack.config.js may solve the problem

@toabey ,slice worked well, but dashboard like this:

and now the sqllab doesn't work:

[hustxiaofeng]

@toabey ,the dashboard is still blank ,and browser console show the error:

dataTables.bootstrap.js?fffa:47Uncaught TypeError: Cannot read property 'defaults' of undefined(anonymous function)

@toabey ,thanks to your tips, solved my problem, but the dashboard is still blank ,and browser console show the error, all related about dataTable, i find that in the dist js files, for example, in dist/dashboard.xx.js, the datatable.net.bs is loaded as AMD:

the if statement get a true const, but in datatable.net.bs's node modules, the if statement is a express as "typeof define === 'function' && define.amd", the npm run dev replace the express as 'true' in output dist js, i attemp to modify it as false in dist js file, and then it works well, but i don't know what cause the issue. i find other js error almost the same related to datatable in webpack:

[tryer3000]

got the same error after login.
webpack fail to load datatable
here's some clues to this problem

This is part of a larger PR where we are renaming the project. Had to nuke my node_modules at some point and hit the same issues you guys were having

[github35]

I encountered the same error when I install Superset and tried to load caravel.db...

[mistercrunch]

@github35 can you try off of the current master ?

[github35]

@mistercrunch I installed 0.13.0 and encountered another problem -- I only have css-theme.0.12.0.entry and other 0.12.0 files in dist folder. So it's not working from my side.

[github35]

0.13.1 works. Thank you!!

[hustxiaofeng]

@mistercrunch ,0.13.1 just fix the problem, it is great!

[mistercrunch]

Nice!
