webpack + babel加载器源映射引用空文件 [英] webpack + babel loader source map references empty file

问题描述

我有一个使用Webpack + babel loader捆绑在一起的es6项目. 当我打开devtools时，可以在下面看到"webpack://"及其所有源代码(es6).

I have an es6 project which I bundle using webpack + babel loader. When I open the devtools I can see 'webpack://' and all my sources (es6) underneath.

问题是:断点没有命中，函数引用将我定向到文件名'?d41d

The problems are: breakpoints don't hit and function references directs me to a file name '?d41d

具有以下内容:

undefined


/** WEBPACK FOOTER **
 ** 
 **/

如果我从文档脚本中向下钻取到捆绑软件中的某个函数，我也将找到?d41d文件

if I drill down from document script to a function in my bundle I get to the ?d41d file as well

我的webpack.config.js:

my webpack.config.js:

module.exports = {

    debug: true,
    devtool: 'cheap-module-eval-source-map',
    entry: "entry.js",
    output: {
        path: "C:/html5/",
        filename: "bundle.js"
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel',
                query: {
                    presets: ['es2015'],
                    plugins: ['transform-object-assign'],
                    sourceMaps: ['inline']
                }
            }
        ]
    }
};

和package.json的一部分，以防万一:

and part of package.json in case it might help:

"devDependencies": {
    "ava": "^0.16.0",
    "babel-core": "^6.14.0",
    "babel-loader": "^6.2.5",
    "babel-plugin-transform-object-assign": "^6.8.0",
    "babel-preset-es2015": "^6.13.2",

    "yargs": "^5.0.0"
  },
  "dependencies": {

  }

谢谢.

Babel引入了不同的源地图格式此处，并且Webpack无法正确处理它.
该修补程序已合并到此PR 中，并在 Webpack 1.14.0 .

Babel introduced a different sourcemap format here and Webpack didn't handle it correctly.
