javascript - Webpack 模块警告 : Failed to parse source map from "data" URL

Question

我收到了令人沮丧的警告，并且无法找到可用的解决方案:

WARNING in ../lensing/dist/main.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from "data" URL: data:application/json;charset=utf-8;base64,eyJ2ZXJza [...]

我的 webpack.config.js 看起来像(为 npm 模块设置):

module.exports = {
    entry: './src/index.js',
    output: {
        filename: 'main.js',
        path: path.resolve(__dirname, 'dist'),
        library: 'lensing',
        libraryTarget: 'umd',
        umdNamedDefine: true
    },
    module: {
        rules: [
            {
                test: /\.m?js$/,
                exclude: /(node_modules|bower_components)/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env'],
                        plugins: [
                            '@babel/plugin-proposal-class-properties'
                        ]
                    }
                }
            },
            {
                test: /\.js$/,
                enforce: 'pre',
                use: ['source-map-loader'],
            },
            {
                test: /\.(png|jpg|gif|svg)$/i,
                use: [
                    {
                        loader: 'url-loader',
                        options: {
                            limit: 8192,
                        },
                    },
                ],
            }
        ]
    },
    stats: {
        warningsFilter: [/Failed to parse source map/],
    },
};

我很惊讶在这个特定问题上没有找到太多其他内容，并且担心我错过了一些通常很简单的事情。我很高兴包含任何其他可能有用的代码片段，但我希望错误代码可能是一个强有力的指标。
任何建议都将受到热烈欢迎!

更好的方法。以下保留源 map ，并仅删除垃圾邮件警告。 From the docs
