Webpack热中间件不能在Ubuntu上使用React进行热重新加载吗?

我遇到了一个非常令人沮丧的问题,我的webpack-hot-middleware并没有热重新加载#39;它正在构建项目,并在我对任何有问题的文件进行任何编辑时重建项目,但它似乎永远不会显示任何更改,并且总是在对它们进行编辑之前显示我的文件(几乎就像是缓存它们或东西)。

我也在使用Express服务器,对所有这些都是新手。我实际上是在尝试使用从雇主那里交给我的文件来设置一个开发环境,并且很难弄清楚如何解决这个问题。

我的package.json运行这些脚本:

"scripts": {
"postinstall": "npm run prod",
"prod": "webpack --config ./webpack.prod.config.js",
"start": "node ./app_build.js"
 }

在" npm install"之后,它似乎运行了这个文件" webpack.prod.config.js":

const path = require('path');
const webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
  devtool: 'source-map',

  entry: './main.js',

  output: {
    path: path.join(__dirname,'prod'),
    filename: 'bundle.js',
    publicPath: '/'
  },

  plugins:[
      new webpack.DefinePlugin({
          'process.env':{
              NODE_ENV: JSON.stringify('production'),
          }
      }),
      new webpack.optimize.DedupePlugin(),
      new webpack.optimize.UglifyJsPlugin({
        minimize: true,
        compress:{
          warnings:false
        }
      }),
      new ExtractTextPlugin('bundle.css'),
      new webpack.IgnorePlugin(/^(buffertools)$/) //Remove deeper dependancy for react-jsonschema-forms error
  ],

  module: {
    loaders: [
      { test: /\.js$/,
        loader: 'babel',
        exclude: /node_modules/,
        query: {
          presets: ['es2015', 'react'] }},
      { test: /\.css?$/,
        loader: ExtractTextPlugin.extract('style', 'css')},
      { test: /\.less$/,
        loader: 'style!css!less' },
      { test: /\.(png|jpg|gif)$/,
        loader: 'url-loader?limit=100000' },
        {
            test: /\.woff(\?v=\d+\.\d+\.\d+)?$/,
            loader: "url?limit=10000&mimetype=application/font-woff"
        }, {
            test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/,
            loader: "url?limit=10000&mimetype=application/font-woff"
        }, {
            test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
            loader: "url?limit=10000&mimetype=application/octet-stream"
        }, {
            test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
            loader: "file"
        }, {
            test: /\.svg(\?v=\d+\.\d+\.\d+)?$/,
            loader: "url?limit=10000&mimetype=image/svg+xml"
        }
    ]
  }
};

" npm start"运行" app_build.js"看起来像这样:

const Server = require('./server.js');
const port = (process.env.PORT || 3333);
const app = Server.app();
const stormpath = require('express-stormpath');
const path = require('path');
var helpers = require('express-stormpath/lib/helpers');
var uuid = require('node-uuid');
var requestProxy = require('express-request-proxy');
var btoa = require('btoa');
var session = require('express-session');
var request = require('request');
var bodyParser = require('body-parser');
var Mailgun = require('mailgun-js');
request = request.defaults({jar:true});

const CONSTANTS  = require('./src/constants/Constants');


//console.log('version: '+ process.env.NODE_ENV);

if (process.env.NODE_ENV !== 'production') {
    const webpack = require('webpack');
    const webpackDevMiddleware = require('webpack-dev-middleware');
    const webpackHotMiddleware = require('webpack-hot-middleware');
    const config = require('./webpack.dev.config.js');
    const compiler = webpack(config);

    app.use(webpackHotMiddleware(compiler));
    app.use(webpackDevMiddleware(compiler, {
        noInfo: true,
        publicPath: config.output.publicPath
    }))
    console.log(`Listening at http://localhost:${port}`);
}

此文件还有更多,但我相信我的问题与我的publicPath或其他东西有关,我不完全确定。就像我说的那样,我从之前的开发人员手中接过了这个配置,我对这一切都是全新的。

有一个similar issue 在ubuntu上尝试命令。使用后热重装工作:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

我发现问题归结为愚蠢的人为错误:我 sudo npm install '编辑了我的所有软件包,我想我只需要做 sudo npm start 为了允许webpack访问文件。只是一个正常的“npm start”就不会让热重载函数按预期运行。
