react-slick: Import CSS from slick-carousel fails

问题

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: {
                  importLoaders: 1,
                  modules: 1,

                },
              },{
                loader: require.resolve('postcss-loader'),
                options: {
                  // Necessary for external CSS imports to work
                  // https://github.com/facebookincubator/create-react-app/issues/2677

                  plugins: () => [
                    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'
                }
              }
            ],
          }

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;
    }
}

you might have missed this:

npm install slick-carousel

回答3:

you change to be this :

import "slick-carousel/slick/slick.css";

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

delete ~

回答4:

You Also need to install slick-carousel for css and font. That's the trick here. Cheers...

npm install slick-carousel --save

Then import css files in your App.js file.

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

回答5:

You need to have appropriate loaders. Use style-loader in combination with css-loader for the CSS. Use file-loader and url-loader in order to load the fonts and images linked within CSS files.

(Here are configuration settings for the file-loader)

So at the end, your webpack.config.js should contain something like this:

module: {
    rules: [
        {
            test: /\.js$/,
            exclude: /node_modules/,
            use: {
                loader: "babel-loader",
                options: {
                    presets: [
                        "@babel/preset-env",
                        "@babel/preset-react"
                    ].map(require.resolve)
                }
            }
        },
        {
            test: /\.css$/,
            use: [
                {loader: "style-loader"},
                {loader: "css-loader"}
            ]
        },
        {
            test: /\.(png|jpg|gif)$/i,
            use: [
                {
                    loader: 'url-loader',
                    options: {
                        limit: 8192
                    }
                }
            ]
        },
        {
            test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
            use: [{
                loader: 'file-loader',
                options: {
                    name: '[name].[ext]',
                    outputPath: 'fonts/'
                }
            }]
        }
    ]
},

After that, you can simply import styles into your application entry point (e.g. /src/index.js):

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

回答6:

It fails because you are importing css modules in your app, and styles from slick are not applied because they are getting cached. I've fixed it in my project like below:

In your style.scss files put this

:global {
    @import 'node_modules/slick-carousel/slick/slick';
}
