Node.js 为什么生成html文件时出错？

我试图读取“project/lib/viewer\u lib/templates”目录中的所有子文件夹和文件，但出现错误。如果我试图读取此目录文件夹中具有特定名称的文件，那么我可以这样做。下面是网页代码。我将非常感谢你的帮助。 下面的代码创建了html文件，但是生成的文件不正确，也就是说，它们没有正确地收集在html中，我需要修复它。 项目文件夹结构：

• /计划
  • /资产
    • webpack.config.js
    • B.法律改革委员会
    • 包装
    • /js
      • app.js
  • /浏览器
    • /模板
    • /登录
      • login.pug
      • 帕格
    • /主要
      • 哈巴狗
      • 哈巴狗
    • /页面
      • 帕格
  • /普里夫
    • /静止的
    • /js
      • app.js
      • app.css
      • index.html

使用FLASH库，它会将错误传递给视图

我无法用这种方法解决它，但下面的代码解决了我的问题。 我只是想把所有的东西分成不同的函数，但我对此感到困惑

const dirpath = "../lib/viewer_web/templates";

function generateHtmlPlugins(templateDir) {
  const templateFolds = fs.readdirSync(path.resolve(__dirname, templateDir));
  return templateFolds.map(name_fold => {
    const templates = fs.readdirSync(path.resolve(__dirname, `${templateDir}/${name_fold}`));
    return templates.map(files => {
      const parts = files.split(".");
      const name = parts[0];
      const extension = parts[1];
      return new HtmlWebpackPlugin({
        filename: `${name}.html`,
        template: path.resolve(__dirname, `${templateDir}/${name_fold}/${name}.${extension}`)
      });
    });
  });
}

const htmlPlugin = generateHtmlPlugins(dirpath);
let rendering = [];
htmlPlugin.map(x => x.map(y => rendering.push(y)));

你能更详细地谈谈吗？我找不到那个图书馆。
