react-slick: Import CSS from slick-carousel fails

React beginner here. My app uses create-react-app, and I'm pulling in react-slick for a carousel. I'm trying to follow the directions that are provided in the setup for react-slick, but the following doesn't work for me:

@import "~slick-carousel/slick/slick.css"; @import "~slick-carousel/slick/slick-theme.css";

I get the following error:

./src/components/Homepage.scss Module not found: Can't resolve '~slick-carousel/slick/slick.css' in '/Users/simon/Dev/frischideas/site-new/src/components'

It works if I add the css to index.html from the CDN, but I'd rather avoid that network call, as I believe it's affecting the rendering of the page on initial load.

I tried following the instructions for configuring create-react-app to use relative paths, but that wasn't working for me either. Maybe I'm completely misunderstanding, but I thought the ~ notation would allow me to import scss from a package in /node_modules.

Any suggestions/clarification would be greatly appreciated.

Update: adding the setup from my webpack.config file (most of which is the default from create-react-app).

            test: /\.scss$/,
            use: [
              require.resolve('classnames-loader'),
              require.resolve('style-loader'), {
                loader: require.resolve('css-loader'),
                options: {

                },
              },{
                loader: require.resolve('postcss-loader'),
                options: {
                  // Necessary for external CSS imports to work

                    require('postcss-flexbugs-fixes'),
                    autoprefixer({
                      browsers: [
                        '>1%',
                        'last 6 versions',
                        'Firefox ESR',
                        'not ie < 9', // React doesn't support IE8 anyway,'
                      ],
                      remove: false,
                      flexbox: 'no-2009',
                    }),
                  ],
                },
              },{
                loader: require.resolve('sass-loader'),
                options: {
                  outputStyle: 'expanded'
                }
              }
            ],
          }

Solution

I was struggling with this issue and I finally find the solution:

just go inside of your node_modules folder and find slick-carousel folder
inside of that find slick.scss and slick-theme.scss from slick folder and open them up
create two seperate files with names of _slick.scss and _slickTheme.scss inside of your style folders of your project
copy all from slick.scss and slick-theme.scss and put them in your newly created files ( _slick.scss and _slickTheme.scss )
import them in your app.scssfile
now if you are using webpack like me, I'm guessing that you getting can't resolve './ajax-loader.gif' error and can't resolve font error after that
in fact those files is been used by slick-carousel css it self and for that we can just simple go inside your newly created _slickTheme.scss and find these lines

/* Slider */

.slick-list {
    .slick-loading & {
        background: #fff slick-image-url("ajax-loader.gif") center center no-repeat;
    }
}

/* Icons */
@if $slick-font-family == "slick" {
    @font-face {
        font-family: "slick";
        src: slick-font-url("slick.eot");
        src: slick-font-url("slick.eot?#iefix") format("embedded-opentype"), slick-font-url("slick.woff") format("woff"), slick-font-url("slick.ttf") format("truetype"), slick-font-url("slick.svg#slick") format("svg");
        font-weight: normal;
        font-style: normal;
    }
}
