找不到模块：错误：无法解析“./@fortawesome/fontawesome-free/css/fontawesome.css”

Question

我正在尝试在 webpack 4 中使用font-awesome 5.1.0。webpack配置文件的内容：

const HtmlWebPackPlugin = require("html-webpack-plugin");
const CopyWebpackPlugin = require("copy-webpack-plugin");
const path = require("path");
const autoprefixer = require('autoprefixer');

module.exports = {
  entry: ["./src/index.js", "./src/index.scss", "react-hot-loader/patch"],
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bundle.[hash].js"
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader",
          options: {
            presets: ["@babel/preset-env", "@babel/preset-react"]
          }
        }
      },
      {
        test: /\.html$/,
        use: [
          {
            loader: "html-loader",
            options: {
              minimize: true
            }
          }
        ]
      },
      {
        test: /\.(sass|scss)$/,
        use: [
          {
            loader: "file-loader",
            options: {
              name: "bundle.css"
            }
          },
          { loader: "extract-loader" },
          {
            loader: "css-loader"
          },
          {
            loader: "postcss-loader",
            options: {
              plugins: () => [autoprefixer({ grid: false })]
            }
          },
          {
            loader: "sass-loader",
            options: {
              includePaths: ["./node_modules"]
            }
          }
        ]
      },
      {
        test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
        use: [
          {
            loader: "file-loader",
            options: {
              name: "[name][hash].[ext]",
              outputPath: "fonts/"
            }
          }
        ]
      }
    ]
  },
  plugins: [
    new HtmlWebPackPlugin({
      template: "./public/index.html",
      filename: "./index.html"
    }),
    new CopyWebpackPlugin([
      {
        from: "public"
      }
    ])
  ]
};

在index.scss文件中：

@import "@fortawesome/fontawesome-free/css/fontawesome.css";
@import "@material/button/mdc-button.scss";
@import "@material/drawer/mdc-drawer.scss";
@import "@material/top-app-bar/mdc-top-app-bar.scss";
@import "@material/list/mdc-list.scss";
@import "./App/scss/app.scss";


* {
  padding: 0;
  margin: 0;
}

html, body {
  height: 100%;
  width: 100%;
}

#root {
  display: flex;
  flex-direction: row;
  box-sizing: border-box;
  height: 100%;
  width: 100%;
}

正如你在图片上可以看到的：

Font-awesome 是从正确的位置导入的，但我遇到了编译器错误：

ERROR in ./src/index.scss
Module not found: Error: Can't resolve './@fortawesome/fontawesome-free/css/fontawesome.css' in '/home/developer/Desktop/reasonreact/cockpit/src'
 @ ./src/index.scss
 @ multi (webpack)-dev-server/client?http://localhost:9000 webpack/hot/dev-server ./src/index.js ./src/index.scss react-hot-loader/patch   

我究竟做错了什么？

更新

我将 webconfig 更改为：

  {
    test: /\.(sass|scss)$/,
    use: [
      {
        loader: "file-loader",
        options: {
          name: "bundle.css"
        }
      },
      { loader: "extract-loader" },
      {
        loader: "css-loader"
      },
      {
        loader: "postcss-loader",
        options: {
          plugins: () => [autoprefixer({ grid: false })]
        }
      },
      {
        loader: "sass-loader",
        options: {
          includePaths: ["./node_modules", "src", "."]
        }
      }
    ]
  },

我有以下错误：

ERROR in ./src/index.scss
Module build failed (from ./node_modules/extract-loader/lib/extractLoader.js):

Answer 1

这个导入路径似乎很混乱..

ERROR in ./src/index.scss
Module not found: Error: Can't resolve './@fortawesome/fontawesome-free/css/fontawesome.css' in '/home/developer/Desktop/reasonreact/cockpit/src'
 @ ./src/index.scss

它并不是在你的node_modules文件夹中寻找令人惊叹的东西。

您可以明确尝试从node_modules导入它吗？

例如...

@import "../path/to/node_modules/@fortawesome/fontawesome-free/css/fontawesome.css";

另外，我认为它不在 node_modules 中查找的原因是因为 webpack 需要有一个 SASS 加载器配置条目，你有一个，但我很好奇你的路径中的点符号是否会以某种方式抛出 webpack。你也可以尝试下面的方法吗？

   /**
   * Config sassLoader paths for imports from node_modules
   */
  sassLoader: {
    includePaths: [
      'node_modules', 'src', '.'
    ]
  },
