我尝试导入名为＆＃34; pageres＆＃34;的节点包模块。 （https://github.com/sindresorhus/pageres）使用Phantom.JS截取用户定义的网页截图。我使用NPM成功安装了pageres，但是在尝试将模块导入到我的项目中时，它抛出了以下例外：＆＃34;无法解析模块＆＃39; child_process＆＃39;＆＃34;，＆＃34;无法解析模块＆＃39;＆＃39;＆＃34;和＆＃34;无法解析模块＆＃39; net＆＃39;＆＃34;。在研究这个问题时，我发现（https://github.com/cytoscape/cytoscape.js/issues/998）解决方法是将以下代码片段添加到我的webpack配置文件中：
node: {
fs: "empty",
child_process: 'empty',
net: 'empty'
}
问题是，这样做可以清除阻止webpack编译代码的错误，但现在我的应用程序根本没有渲染。
是否有任何可用的解决方法可以解决此问题，任何人都可以解释为什么我之前遇到的错误＆＃34;无法解决模块＆＃39; child_process＆＃39;＆＃34;来了吗？
附注：我使用React-Redux-Universal（https://github.com/erikras/react-redux-universal-hot-example）作为我的锅炉，因此React.JS正在处理我的观点。
