我的项目有两种不同的Webpack配置-一种具有输出intro.js，一种具有输出app.js。我正在尝试使热模块更换（HMR）工作，但遇到以下问题：
当更改与一种配置相关的代码时，webpack仅为该配置生成相关的hot-update。在这种情况下，仅适用于哈希8c45d20a9bf289f9ebe1：

但是，HMR客户端尝试查找两个散列的更新文件-8c45d20a9bf289f9ebe1和436897b06fc9e0056f80。
由于前者存在而后者不存在，因此Webpacks HMR总是完全重新加载页面，这与HMR的目的背道而驰。
我觉得问题是两件事之一
- 即使只有一个更改，Webpack也不会为所有配置生成热更新json
- 即使该配置的相关文件均未更改，Webpack也会尝试访问
intro.js热更新json。
如何解决此问题并在不需要时阻止整页重新加载？
这是我的一些主要代码
...
devserverOptions = {
public: `${host}:${options.port}`,disableHostCheck: true,hot: true,inline: true,contentBase: path.resolve(projectRoot),stats: { colors: true },},...devserverOptions
};
const configs = [introBaseConfig,appBaseConfig];
configs.forEach((config,index) => {
// Add to the current entry two additional entries
config.entry = [`webpack-dev-server/client?http://${host}:${options.port}`,'webpack/hot/only-dev-server',].concat(Array.isArray(config.entry) ? config.entry : config.entry);
// Add the hot module replacement plugin
config.plugins = [
new webpack.HotModuleReplacementPlugin()
];
delete config.output.path;
// this is where 'hot' updates will be fetched from
config.output.publicPath = `http://${host}:${options.port}${webpack_output_path}/`;
});
const server = new Webpackdevserver(webpack(configs),devserverOptions);
