Webpack build/dev errors

Open Berkmann18 opened this issue 7 years ago • 1 comments

Not sure if it's to do with the deprecation that webpack had (which changes how build/dev processes work) or to do with babel (which if I recall correctly recommend using the babel-plugin-env instead of babel-plugin-es2015 since Babel v7). I'm trying to run npm run build and npm run dev which respectively outputs:

EDIT: After looking at the module list (npm ls --depth=0), I noticed this:

After updating some dependencies, I now get this for npm run build:

Which makes me think that index.js should be changed accordingly.

Here's what npm run dev gives:
