Node.js 在Vagrant Ubuntu机器上配置Websocket、Nodejs和Webpack

问题

在过去的几天里，我一直在努力让我的

react hot loader

在运行Ubuntu-

14.04

的流浪机器上工作。但是，每当我配置

webpack-dev-server

在同一

主机：端口上运行时（
'webpack-dev-server/client？http://0.0.0.0:80/“，
）作为我的流浪机器，我不断遇到以下错误：


配置-webpack config.js

    if (err) {
        console.log(err);
    }

  console.log('Listening at localhost:8080');
});

结论

我有一个反向代理，它将
8080
移植到我的服务器当前运行的
80
。如果我尝试在端口
8080
中运行
webpack dev server
，我会得到一个被拒绝的连接，这是没有意义的，但是使用端口
80
似乎可以正常工作

我最初的直觉告诉我这可能是一个
apache2
配置问题，因为我曾尝试使用许多不同的样板项目来验证问题，这些样板项目假定是
开箱即用的，这确实是我的一个配置问题
