Webpack - sass loader cannot find images

问题

The sass loader doc says: "If you're just generating CSS without passing it to the css-loader, it must be relative to your web root". So i did as it tells, I have my index.html in my project root, then I'm trying to load an image from my scss file. Now I have 2 errors: 1) from Chrome's console: Cannot find module "./img/header.jpg". 2) from my terminal:

ERROR in ./~/css-loader!./~/sass-loader!./~/resolve-url-loader!./public/css/header.scss
Module not found: Error: Cannot resolve 'file' or 'directory' ./img/header.jpg in C:\Web-Development\React\Portfolio\public\css
 @ ./~/css-loader!./~/sass-loader!./~/resolve-url-loader!./public/css/header.scss 6:64-91

webpack.config.js

module.exports = {
    entry: './main.jsx',
    output: {
        filename: './public/js/build/bundle.js'
    },
    module: {
        loaders: [
            {
              test: /\.jsx?$/,
              exclude: /(node_modules|bower_components)/,
              loader: 'babel',
              query: {
                  presets: ['react', 'es2015']
              }
          },
          {
              test: /\.scss$/,
              loaders: ["style", "css", "sass", "resolve-url"]
          },
          {
            test: /\.jpg$/,
            loader: "file?name=[path][name].[ext]"
          }
        ]
    }
};

If I see my code, I can clearly see that my css lives inside <head> so I've pointed my image's path to my root, as documentation says, but still can't fix it.

UPDATE: I've installed file-loader and followed the instructions, now I get this error in console: GET http://localhost:3000/public/img/header.jpg 404 (Not Found) - jquery.js:9119

回答1:

As far as I can see you are actually using the css loader ( "style", "css", "sass", "resolve-url" ) (the "css" part is the "css-loader")

In your sass file(s) you should link to the images using a relative path from the sass file you are editing.

styles
 - somefile.scss
 - another.scss
images
 - someImage.jpg

in somefile.scss, you should link to your image like this:

background-image: url("../images/someImage.jpg);

Do note, that if you want webpack to move those images to your distribution folder (if you are using a system like this) that you will need something like file-loader to copy those files over.

You can use ignore-loader if your images are already in the place where you need them. file-loader will copy the files to your output folder.

To solve this problem I've uploaded this webpack extremly basic configuration to start my projects, I hope it can help everyone who had this problem. Suggestions are all welcome of course.
