javascript - 模块解析失败 : Unexpected character for woff woff2 and ttf file webpack

Question

我有 webpack.config.js 文件并为单个模块 block 中的每种字体类型添加了加载器，但是当我运行 yarn start

webback 在终端中成功地遵守了这些细节

                            index.html  605 bytes          [emitted]  

并且页面在浏览器中打开并应用了 bootstrap css 但在控制台中，它为 woff woff2 和 ttf 提供了多个错误文件(见图片)

Module parse failed: Unexpected character '' (1:4)
You may need an appropriate loader to handle this file type.

我尝试了各种组合来代替来自 github solution 的加载程序的上述模块但它们都不起作用，请参阅试验

试用 1(使用文件加载器)

    { 
      test: /\.(jpg|png|woff|woff2|eot|ttf|svg)$/, 
      loader: 'file-loader?name=[path][name].[ext]?[hash]' 
    }

试验 2(使用 url loader)

    { 
       test: /\.(woff(2)?|eot|ttf|otf)(\?[a-z0-9]+)?$/, 
       loader: 'url-loader?limit=100000' 
    }

试验三(使用带下限的url loader)

        {
            test: /\.(woff2?|ttf|eot|svg|png|jpe?g|gif)(\?v=\d+\.\d+\.\d+)?$/,
            loader: 'url-loader?limit=8192'
        },

Answer 1

在 webpack 4 中，你需要:

{
 test: /\.(woff|woff2|ttf|eot)$/,
 use: 'file-loader?name=fonts/[name].[ext]!static'
}

例如使用文件加载器。
