Your method of importing debug results in an error
Closed this issue · 3 comments
When I try to import and use debug the way you are:
import debug from 'debug';
const log = debug('app:log');
It results in the error Module "..../debug/index" has no default export.
. I have to import it like this:
import * as debug from 'debug';
which then results in a rollup error:
Cannot call a namespace ('debug')
Any idea what the difference might be?
@jasonburrows Hmm... that's odd. Can you share the repo you're working in?
I'd start by checking version numbers; it's possible debug
and/or rollup
have new releases that changed behavior. Beyond that, I'd need to take a look at the code to help troubleshoot.
@jlengstorf Hi - I apologize for not returning and adding to this issue when I learned more.
It turns out that my problems were due to importing @types/debug. If I remove @types/debug, everything works using your suggested method of importing. I'm not sure why, but since I'm not actually using any of the type information offered in @types/debug, I just moved on.
Regardless, it seems to be a bug with @types/debug, not your project, debug, or rollup.
I didn't even think about it - I'm used to just importing that type information and did it on autopilot without considering it may have been the source of the problem.
Thanks for the clarification. Closing this; let me know if it turns out there's something in this config that was interfering with @types/debug
.
