Webpack 热中间件不能使用 React 在 Ubuntu 上热重载?

Webpack Hot Middleware not hot-reloading on Ubuntu with React?

我 运行 遇到了一个非常令人沮丧的问题,我的 webpack-hot-middleware 不是 'hot reloading'。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,但它似乎从不显示任何更改并且始终在对它们进行编辑之前显示我的文件(几乎就像它正在缓存它们或东西)。

我也在使用 Express 服务器,而且对这一切还很陌生。实际上,我正在尝试使用雇主交给我的文件来设置开发环境,但我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"
 }

后一个"npm install",好像运行这个文件"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"
        }
    ]
  }
};

一个 "npm start" 运行s "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}`);
}

这个文件还有更多内容,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,我是从以前的开发人员那里得到这个配置的,我对这一切都是全新的。

有一个
在 ubuntu 上尝试命令。热重载在我使用后有效:
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 安装了我所有的包,我想我只需要做 sudo npm start 以允许 webpack 访问这些文件。只是一个普通的 "npm start" 不会让热重载功能按预期运行。
