我的问题是，无论我做什么，我都会在wepack_hmr上获得404，我无法为我的生活找出原因，为什么它不可用。
完整的Webpack配置

它需要我的运行，但它不是：/
答案 0 :(得分：1)
好的，所以人们很容易看到我做了什么让它在这里工作它是：
我认为我更容易完全删除scss并且开箱即用css模块。这似乎有很大帮助。
我用git@github.com：christianalfoni / webpack-express-boilerplate.git帮我指导自己。知道我有一个工作的东西实际上教会了我比在webpack之前我最有可能学到的东西。你可以猜到这不是很多：D
另一个真正有用的主要变化就是改变路径并不令人惊讶。但是这些与我之前读过的output.path中的路径性有关，但认为这与wepack.config.js有关，而不是那里的东西都算作文档根，即使对于html和css也是如此。
**关键部分:) **
我还必须更新我的快速设置，因为我没有给它express.static路径......哦，我的愚蠢，我怎么能错过这样一个基本的东西......所以：
<强>快速
app.use(express.static(__dirname + '/public/')); //Don't forget me :(

我实际上已经两次发布相同的答案。但它们都是相关的。可悲的是:(
