hmm. I'm getting an error when I check out this branch, run npm install, npm run dev and then npm run lint-css:

> wp-scripts lint-style '**/*.scss'

I'm also getting a package-lock.json change when I run npm install in this branch:

• node version: 10.16.2
• npm version: 6.9.0

@nerrad Do you have a node-modules folder in packages/scripts ?

Removing that folder and running npm install from that folder should resolve the issue

It looks like the issue @nerrad has is legitimate:
https://travis-ci.com/WordPress/gutenberg/jobs/223922463

I don't see stylelint changes in package-lock.json file. I spent some time trying to document how we should make those updates of dependencies less problematic:
https://github.com/WordPress/gutenberg/tree/master/packages#managing-dependencies

I still want to test whether manual version change in the corresponding package.json file with lerna bootstrap wouldn't be even simpler to use.

Strange, as I did follow the new process to to update the lock file, I had to do this a half dozen times to get it right, the lock file in this PR appears to have the changes I would expect to see:

https://github.com/WordPress/gutenberg/pull/16985/files#diff-32607347f8126e6534ebc7ebaec4853d

I probably won't have time to look at this before the end of the week, so if anyone feels like playing some package lock debug, feel free to 😏

[gziolo]

We still need to make Travis happy before we can land it.

[gziolo]

Can we include some notes in the package's CHANGELOG file?
