一直在尝试研究这个，但似乎没有其他人有这个，或者认为这是一个问题。

我在我mini-css-extract-plugin的.MiniCssExtractPluginwebpack.config.js

但是，当我运行webpack控制台时，会出现数百个类似的实例......

Child mini-css-extract-plugin ../../../node_modules/css-loader/index.js??ref--6-1!../../../node_modules/postcss-loader/src/index.js!../../../node_modules/sass-loader/lib/loader.js!ui/radiolist-toggler/RadioListToggler.scss:
    Entrypoint mini-css-extract-plugin = *
    [../../../node_modules/css-loader/index.js?!../../../node_modules/postcss-loader/src/index.js!../../../node_modules/sass-loader/lib/loader.js!./ui/radiolist-toggler/RadioListToggler.scss] /Users/~~~/git/user-section/node_modules/css-loader??ref--6-1!/Users/~~~/git/user-section/node_modules/postcss-loader/src!/Users/~~/git/user-section/node_modules/sass-loader/lib/loader.js!./ui/radiolist-toggler/RadioListToggler.scss 5.33 KiB {mini-css-extract-plugin} [built]
        + 1 hidden module

我需要向上滚动几秒钟才能看到我的所有资产等。

我对 webpack 很陌生，所以不完全确定如何防止它被输出到控制台？

下面是我的webpack.config.js

const webpack = require('webpack');

const CleanWebpackPlugin = require('clean-webpack-plugin');

@mcclosa 将此作为评论提到，但如果有人看到这个问题，看不到答案并点击离开，解决方案是将stats选项添加到您的webpack.config.js文件中，如下所示：

module.exports = {
   stats: { children: false },
}

上面的选项使用了children: false@mcclosa 建议的选项，它确实成功地删除了 mini-css-extract-plugin 的垃圾输出，但我发现使用预设stats: "minimal"会产生更好的整体输出。使用：

module.exports = {
   stats: "minimal",
}

..只要我的构建没有错误，就会给我以下微小的输出：

i ｢wdm｣: Compiling...
i ｢wdm｣:    69 modules
i ｢wdm｣: Compiled successfully.

..而不是几十行无用的构建数据，但是当出现错误时它会继续给出错误信息。

不幸的是，mini-css-extract-loader 没有设置来控制其日志输出的详细程度。

设置stats.children为false或"minimal"您webpack.config.js可以删除许多其他有用的输出，例如您的包名称和大小、入口点信息、构建时间、您可能想要保留的其他插件的合法警告和错误等。

相反，似乎我们必须添加一个在编译器挂钩上执行的插件，以从与 mini-css-extract-plugin 关联done的对象中删除项目。stats.compilation

这个示例插件应该可以工作：

class CleanupMiniCssExtractPlugin {
  apply(compiler) {
    compiler.hooks.done.tap("CleanupMiniCssExtractPlugin", stats => {
      if (this._children) {
        const children = stats.compilation.children;
        if (Array.isArray(children)) {
          stats.compilation.children = children.filter(
            child => child.name.indexOf("mini-css-extract-plugin") == -1
          );
        }
      }
    });
  }
}

或者你可以使用这个 npm 包：https ://www.npmjs.com/package/cleanup-mini-css-extract-plugin
