以下一些细节可能有用： 环境和工具 openjdk版本“ 1.8.0_232” OpenJDK运行时环境（内部版本1.8.0_232-8u232-b09-1〜deb9u1-b09） OpenJDK 64位服务器VM（内部版本25.232-b09，混合模式） -git版本2.11.0 -节点：v12.13.1 -npm：6.13.4 -约曼：3.1.1

在Debian 9上运行它（拉伸）任何帮助将不胜感激，谢谢。

失败与eslint有关，所以我想当您运行npm时它也会失败运行皮棉？作为临时解决方法，并确认存在问题使用eslint可以注释掉eslint-loader规则配置在webpack / webpack.dev.js中，如下所示？

module: {
    rules: [ /* {
        test: /\.(j|t)s$/,
        enforce: 'pre',
        loader: 'eslint-loader',
        exclude: /node_modules/
    }, */

任务：webpack失败，无法读取未定义的属性“ forEach”
