I get this error when running bash serve.sh from cmd/management-console/web:

  /Users/chrismwendt/github.com/sourcegraph/sourcegraph/cmd/management-console/web/src/CriticalConfigEditor.scss:1:1: Cannot resolve dependency '/Users/chrismwendt/github.com/sourcegraph/sourcegraph/cmd/management-console/web/node_modules/@sourcegraph/react-loading-spinner/lib/LoadingSpinner.css' at '/Users/chrismwendt/github.com/sourcegraph/sourcegraph/cmd/management-console/web/node_modules/@sourcegraph/react-loading-spinner/lib/LoadingSpinner.css'
    at Resolver.resolve (/Users/chrismwendt/github.com/sourcegraph/sourcegraph/cmd/management-console/web/node_modules/parcel-bundler/src/Resolver.js:70:17)

It looks like Parcel is saying a file that exists doesn't exist 😕 Any idea why?

Will take a look locally soon.

Apologies, I ran out of time last night to take a look into this one. Maybe @attfarhan or @ijsnow might have quick ideas about why the import isn't working here?

[ijsnow]

Fixed by adding .sassrc (parcel-bundler/parcel#39). Funny that you need config for a zero config bundler!!! :sarcasm-face:

[ijsnow]

Wait that didn't fix it actually

[ijsnow]

It's possible that @attfarhan fixed this same sort of issue yesterday with bootstrap but I can't remember what the solution was off the top of my head.

This won't get into 3.0, so there's less pressure to implement it soon.
