Code

Not configuration related.

How Do We Reproduce?

• Check the branch stylelint-webpack-plugin-error
• Use stylelint-webpack-plugin with stylelint >= ^11.0.0. If you downgrade stylelint to 10.1.0 it works fine.
• Related issue to configuration change is here

@akoidan could you try to run just stylelint without this plugin? maybe this issue related to stylelint instead of webpack plugin

[akoidan]

@vankop this issue IS related to stylelint, since that changed the API, and it doesn't work with the same code as it did before. The description is in related issue I attached. I guess it's either worth changing the README, specifying the version of stylelint, either support the latest version of stylelint that you have in the readme.

@akoidan I couldn't understand the problem and I couldn't reproduce either

[akoidan]

@akoidan I couldn't understand the problem and I couldn't reproduce either

I attached the repo and mentioned it in the description in the How Do We Reproduce? section. Does it work on your PC? https://github.com/akoidan/vue-webpack-typescript/tree/stylelint-webpack-plugin-error , mind the branch

[ricardogobbosouza]

@akoidan There are several errors and warnings, but none related to this plugin.

[akoidan]

@ricardogobbosouza yeah, I think it's rather related to scss syntax stylelint-scss/stylelint-scss#380

Forwaded to AleshaOleg/postcss-sass#120
