Question

我有几个现有的.js和关联的.map.js（最初由TypeScript构建）。

现在我喜欢Webpack，以及＃34;服务＆＃34;那些。我正在使用此配置：

devtool: "source-map",
module: {
    preLoaders: [
        {test: /\.js$/, loader: "source-map-loader"}
    ],
    loaders: [
        {test: /\.js$/, loader: "react-hot"}
    ]
}

我从这里得到了这个配置：Webpack use existing source map from previous build step

但我得到的是很多警告（即使我安装了source-map-loader）：

WARNING in ./modules/Component.js.map
Module parse failed: /Users/me/project/modules/Component.js.map Unexpected token (1:10)
You may need an appropriate loader to handle this file type.

使Webpack使用现有的源映射
