Current postcss version is incompatible.

[zry656565]

Do you want to request a feature or report a bug?

I don't know, maybe a bug of css-loader or postcss-loader.

What is the current behavior?

$ webpack

Webpack is watching the files…

Your current PostCSS version is 5.2.17, but postcss-modules-scope uses 6.0.1. Perhaps this is the source of the error below.
...
ERROR in ./node_modules/css-loader??ref--5-2!./node_modules/postcss-loader/lib??ref--5-3!./node_modules/less-loader/dist/cjs.js??ref--5-4!./node_modules/prepend-style-loader??ref--5-5!./static_files/libraries/components/LCAlert/Button.less
Module build failed: Error: composition is only allowed when selector is single :local class name not in ".delete", ".delete" is weird
...

What is the expected behavior?

Upgrade postcss version of css-loader to ^6.0.1 please, because another dependency of css-loader, postcss-modules-scope@^1.1.0, relies on postcss@^6.0.1.

And my problem may be fixed.

Please mention other relevant information such as your webpack version, Node.js version and Operating System.

• webpack: 3.10.0
• node: 9.7.1
• OS: macOS 10.13.4
• css-loader: 0.28.10

I had a nasty looking bug in a docker version of my app that upgrading css-loader's postcss module to ^6.0.1 fixed for me:
