node.js npm build之后页面空白页

npm build后编译正常的

但是在项目启动之后，页面就变成了空白页。

项目之前是没有问题的，但是最近下载下来想重新跑一下的时候，就突然页面空白了。试了好多办法都没用，求熟悉的大佬们帮忙

不出意外的话，应该是路径的问题。看看控制台的报错，找到你的根路径，然后根据根路径再去匹配你的样式路径，也算是最佳的方式了，长时间不使用有些杀毒软件会清理掉一些文件。

从浏览器错误日志看，有安全策略等禁止了你的一些热加载什么的，导致页面出问题了

问题补充： 页面是用的react。 packge.json 代码如下：
"name": "wangxiang",
"version": "1.0.0",
"description": "admin",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",

},

关键现在有异常也好，就是没有异常提示。唯一能看到的错误就是空白页面里的什么热加载

问题记录，路径问题，webpack.config.js里面设置跳转路径问题。
