Npm install --production

Dashboard
3

Ah, thanks for raising this.

I managed to totally bork my dev instance just before Christmas and on rebuilding, I installed with --production as well without really thinking through the consequences. I now get warnings like this both in the browser console and on the Node-RED log:

ui_base - error: { [Error: ENOENT: no such file or directory, stat 'C:\src\nr2\data\node_modules\node-red-dashboard\dist\js\gridstack.min.map']
  errno: -4058,
  code: 'ENOENT',
  syscall: 'stat',
  path:
   'C:\\src\\nr2\\data\\node_modules\\node-red-dashboard\\dist\\js\\gridstack.min.map',
  expose: false,
  statusCode: 404,
  status: 404 }

As Dave say's it is only a warning but annoying anyway.
