node.js - 无法运行 npm run build 或 npm start

Question

每当我尝试构建 web-pack 文件或启动 web-pack 开发服务器时，都会出现错误。它正在工作，但我在使用 eslint 时弄乱了一些东西。

这是尝试npm build时的错误包

这是我的 webpack 文件

module.exports = {
  entry: ['babel-polyfill', './app/index.js'],
  output: {
    path: __dirname + '/build',
    // if the above line does not work, try `path: __dirname + '/build'`
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: /\.js$/, // a regular expression that catches .js files
        exclude: /node_modules/,
        loader: ['babel-loader']
      }
    ],
  },
  devServer: {
    port: 3000, // most common port
    contentBase: './build',
    inline: true
  }
};

它似乎没有在我的 webpack.config.js 文件中获取本地脚本 - 但我对此很陌生，并且仍在学习

Answer 1

尝试删除node_modules，然后运行脚本。
