Bootstrap图标和Webpack 5-您可能需要适当的加载器来处理此文件类型

Question

我在让bootstrap图标与webpack合作时遇到了很多麻烦：

获取以下内容：

ERROR in ./node_modules/bootstrap-icons/font/bootstrap-icons.css 1:0
Module parse failed: Unexpected character '@' (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> @font-face {
|   font-family: "bootstrap-icons";
|   src: url("./fonts/bootstrap-icons.woff2?856008caa5eb66df68595e734e59580d") format("woff2"),
 @ ./src/index.js 3:0-50

有了webpack的规定：

      {
        test: /\.((png)|(eot)|(woff)|(woff2)|(ttf)|(svg)|(gif))(\?((v=\d+\.\d+\.\d+)|(\w*)))?$/,
        use: { loader: "file-loader?name=/[hash].[ext]" }
      },
      ...

      {
        test: /\.(sa|sc|c)ss$/,
        exclude: /node_modules/,
        use: [
          "style-loader",
          MiniCssExtractPlugin.loader,
          "css-loader",
          "postcss-loader",
          "sass-loader"
        ]
      }

和.js as

import "./scss/main.scss";
import "bootstrap-icons/font/bootstrap-icons.css";

能找到的我都试过了。我跟踪了这段代码的每一行，但仍然不能让它工作：https://odan.github.io/2021/01/07/webpack-bootstrap-icons.html

webpack: "5.52.1",
"bootstrap-icons": "^1.5.0",
"file-loader": "^6.2.0",

我也有同样的问题，我通过阅读documentation解决了这个问题。后来我发现的问题是，webpack不会用purgecss清除bootstrap中不常见的图标。

  {
    test: /\.(woff|woff2|eot|ttf|otf)$/i,
    type: "asset/inline",
  },
