这些细节可能有用：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。

失败是关于eslint的，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/
    }, */
