Web server example Import Error #2

Closed jacob-lapenna closed 5 years ago

jacob-lapenna commented 5 years ago

After pip install dash dash-renderer dash-html-components dash-core-components and running $ ./web_server.py or $ python web_server.py I get ImportError: cannot import name Event from dash.dependencies. After reading that the Event system was removed (see https://community.plot.ly/t/why-cant-i-import-the-event-dash-dependency/19288), I commented it out in the import statement and naturally got NameError: name 'Event' is not defined on line 389 of web_server.py with no import error. Potential guidance on a fix is detailed here: https://community.plot.ly/t/dash-events-button/19791/3?u=nedned

Thank you for the feedback, I have forwarded this to the web server example developer so we can incorporate the fix.

We have added instructions in the readme for the web server example on how to work around this issue.
