Hi! Thanks for filling the issue, please next time don't delete the template! Couple of questions:

1. You didn't mention the file webpack.config.js in your problem, where does it come from?
2. Why do you use migrate? Looks like you're creating a new project

i have tried to switch to version 2.1.1 - but go the
TypeError: Cannot read property 'length' of null
#542

[evenstensberg]

Which version are you lads at? We need more information 👍

[IzaGz]

this issue error happens on webpack-cli 308

[evenstensberg]

Upgrade to version 3.1.2 and up, an update to the latest version would be the best for you! :)

@ev1stensberg I used following command.

npm i -D webpack-cli@latest

But it is still installing 3.0.8 version

[evenstensberg]

Yep. I'll submit a fix shortly

[evenstensberg]

Fixed on master now. Will publish a new release once @dhruvdutt has fixed the breaking tests in bintestcases.
