当我运行带有 / dist 的publicPath的webpack-dev-server时,可以看到我的应用程序的实时编辑(更改为html,style,js)。但是,当我将应用程序编译到生产版本中时,样式表和javascript将从/dist/main.css和/dist/main.js加载,而不是从main.css和main.js
加载问题似乎出在publicPath设置上。如果删除publicPath,则该应用程序将使用main.css和main.js进行编译,但看不到实时编辑。但是,如果保留 publicPath:/ dist ,我可以看到实时编辑,但是现在我得到 /dist/main.css和/dist/main.js
