【问题描述】：

我在另一台计算机上安装了 React 项目，突然浏览器中的控制台充满了这些：

...

sockjs-client 有很多日志记录，还有热重新加载的日志和我自己的控制台日志。我没有在网上找到任何帮助。

我的package.json

    ]
  }
}

和webpack.config.js

const webpack = require('webpack')
const path = require('path')

module.exports = {
  devtool: 'source-map',
  entry: {
    'app': [
      'babel-polyfill',
      'react-hot-loader/patch',
      './src/index'
    ]
  },
  output: {
    path: path.resolve(__dirname, './dist'),
    filename: '[name].js'
  },
  resolve : {
    extensions: ['.js', '.jsx'],
    modules: [
        path.resolve('src'),
        path.resolve('static'),
        path.resolve('node_modules')
    ]
  },
  plugins: [
      new webpack.DefinePlugin({
          'process.env': {
              NODE_ENV : JSON.stringify('development'),
              BROWSER : JSON.stringify(true)
          }
      }),
  ],
  module: {
    rules: [
      { 
        test: /\.jsx|js$/, 
        exclude: /node_modules/, 
        loader: 'babel-loader' 
      }
    ]
  }
}

【问题讨论】：

它与您的项目（配置）无关，因为这些日志没有显示在您以前的计算机中。使用与以前相同的设置（以前的计算机浏览器控制台）配置您的浏览器控制台，您将获得与以往相同的结果。

标签： javascript node.js webpack console.log sockjs

【解决方案1】：

来自 webpack 的Sockjs 模块正在使用debug 节点模块登录到控制台。环境变量 DEBUG（用于设置 debug 模块）设置为 * 并保存在 localStorage 中。所以我的新项目在localhost:8080 上运行，因为同一台机器上的一些以前的项目使用DEBUG='*'，因此记录。

我尝试将 webpack.config.js 中的 process.env.DEBUG 设置为其他值，但它没有更改 localStorage 中的值，因此它继续记录。所以我只是手动从 localStorage 中删除了值。
