Question

我使用babel-loader，但无法弄清楚如何生成或找到已转换文件的源地图。我尝试了eval-source-map，inline-source-map，source-map。

webpack.config.js

const BowerWebpackPlugin = require("bower-webpack-plugin");

module.exports = {
    entry: './src/script/index.jsx',
    output: {
        filename: 'bundle.js',
        sourceMapFilename: "bundle.js.map",
        publicPath: 'http://localhost:8090/assets'
    },
    debug: true,
    devtool: 'inline-source-map',
    module: {
        loaders: [
            {   
                test: /\.js[x]?$/, 
                loaders: ['react-hot', 'jsx', 'babel'],
                exclude: /node_modules/ 
              },
              {
                test: /\.scss$/,
                loaders: [ 'style', 'css?sourceMap', 'sass?sourceMap' ]
              },
              {
                test: /\.less$/,
                loaders: [ 'style', 'css?sourceMap', 'less?sourceMap' ]
              },
              {
                test: /\.css$/,
                loaders: [ 'style', 'css']
              },
              { test: /\.woff$/,   loader: "url-loader?limit=10000&mimetype=application/font-woff" },
              { test: /\.woff2$/,   loader: "url-loader?limit=10000&mimetype=application/font-woff2" },
              { test: /\.(eot|ttf|svg|gif|png)$/,    loader: "file-loader" }
        ]
    },
    plugins: [
        new BowerWebpackPlugin()
    ],
    externals: {
        //don't bundle the 'react' npm package with our bundle.js
        //but get it from a global 'React' variable
        'react': 'React'
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    }
}

的package.json

    {
    "name": "Won",

    }
}

编辑：//

完成所有这些webpack.config.js后，此package.json对我有效。

EDIT2：//

现在我使用this webpack config

Answer 1

使用webpack-dev-server -d

-d是--debug --devtool source-map --output-pathinfo。
output-pathinfo为生成的包添加注释，说明哪些模块/文件包含在哪些位置。因此，在生成的代码中，注释会添加到以下代码行：require(/* ./test */23)，表示23指向test模块。当您查看Webpack生成的代码时，这非常有用，而不是在单步执行调试器时。我得到了这个例子from this relevant bit of documentation。
这一切都有效，因为webpack-dev-server接受与webpack相同的所有标记。
See this section in the docs了解详情。

提示＆amp;陷阱

--content-base - 默认情况下，开发服务器将在您运行命令的目录中提供文件。如果您的构建文件位于build/，则需要指定--content-base build/以便开发服务器将提供build目录
--inline - 每当您保存文件并进行一些更改时自动重新加载！

Answer 2

使用webpack -d

d标志代表开发快捷方式，它支持所有开发人员工具，例如源地图。

Answer 3

将{devtool:"source-map"}添加到 webpack.config.js

Answer 4

请在webpack.config.js文件中添加以下内容。

devtool：“＃inline-source-map”，

您可以在webpack` https://webpack.github.io/docs/configuration.html

的网站上找到有关它的明确信息

另请参阅webpack网站上的sourcemap部分的附加截图。

Answer 5

我所做的就是改变：

// package.json
{
    ...
    **from** "dev:serve": "webpack-dev-server",
    **to** "dev:serve": "webpack-dev-server -d",
    ...
}

相当于：$ webpack-dev-server -d

现在我可以在Chrome中使用Ctrl + p，我会看到我的ES6语法设置断点。

信息

$ webpack-dev-server --version
webpack-dev-server 2.9.7
webpack 3.10.0

Webpack-dev-server不会生成源映射
