next-css not working with next 6 & next 7

[CYB3RL1F3]

Bug report

Impossible to load style from node_module react-slick.

Describe the bug

Receive this message :

Module build failed (from app/node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleParseError: Module parse failed: Unexpected character '' (1:0)
You may need an appropriate loader to handle this file type.
(Source code omitted for this binary file)

To Reproduce

apply next.config.js like following :

module.exports = withCss(withTypescript({
    distDir: '../dist',
}));

Also tried :

const wcss = withCss({
    server: true
});

module.exports = withTypescript({
    distDir: '../dist',
    ...wcss
});

I tried options like modules, etc...
The CSS file is loaded from a node_module.
Important : we are in a lerna context. The component using the css is in UI and called from main-app. The typescript is configured in UI (that's why there is only distDir in the typescript options).

Steps to reproduce the behavior, please provide code snippets or a repository:
with next 7.0.0 and next-css 1.0.0

System information

• Version of Next.js: [e.g. 7.0.0]

Additional context

Add any other context about the problem here.

Please show how you are referencing the actual stylesheet.

using import :

import 'slick-carousel/slick/slick-theme.css';
import 'slick-carousel/slick/slick.css';

I also tried the following way :

const withPlugins = (nextConfig = {}) => {
    return Object.assign({}, nextConfig, {
        webpack(config, options) {
            if (!config.plugins) config.plugins = [];
            config.plugins.push(
                new MiniCssExtractPlugin({
                    filename: 'style.css',
                    chunkFilename: '[name].css'
                })
            );
            config.module.rules.push({
                test: /\.css$/,
                use: [
                    {
                        loader: MiniCssExtractPlugin.loader,
                        options: {
                            publicPath: './static'
                        }
                    },
                    {
                        loader: 'css-loader',
                        options: {
                            modules: true,
                            sourceMap: true
                        }
                    }
                ]
            });

            if (typeof nextConfig.webpack === 'function') {
                return nextConfig.webpack(config, options);
            }

            return config;
        }
    });
};

And have as result :

Unexpected token .
site/node_modules/slick-carousel/slick/slick.css:2
.slick-slider
^

SyntaxError: Unexpected token .

I really need CSS in the project. A clue ?

@CYB3RL1F3 it may be related to this issue #77 since you are also using typescript too.

[dptoot]

It appears this would be the issue.

webpack-contrib/mini-css-extract-plugin#282

Removing @font-face declarations work for me (although I need them)

+1 doesn't work for me either (next 7.0.1, @zeit/next-css 1.0.1)

TypeError: Cannot destructure property `createHash` of 'undefined' or 'null'.

[olastor]

A quick fix for me was adding webpack as a dependency, using yarn add webpack

Same issue here but only on Windows 10 with Cygwin. When I switch to Ubuntu on Windows Linux Subsystem it works fine. Same project, same node_modules.

Hi, thanks for creating an issue. We currently recommend using https://nextjs.org/docs/basic-features/built-in-css-support as the plugins have been deprecated in favor of the built-in support.
