Uglify源地图无法在Chrome中运行（但适用于IE11和Firefox）

Question

我有一个使用grunt，browserify和uglify的SPA ASP.NET项目。当我尝试在Chrome调试器中查看JavaScript时，它会显示缩小的JavaScript并且似乎忽略了地图文件。在IE11和Firefox中，调试器正确显示未分析的JavaScript。我确认在Chrome选项中选中了“启用JavaScript源地图”。

在Chrome中，缩小文件的最后一行是：

//# sourceMappingURL=bundledApp.min.js.map

这是我的完整gruntfile：

module.exports = function (grunt) {

grunt.initConfig({
    clean: ['dist'],
    browserify: {
        build: {
            files: {
                "dist/bundledApp.js": [
                    './Scripts/jquery-2.1.4.js',
                    './Scripts/underscore.js',
                    './Scripts/backbone.js',
                    './App/App.js',
                    './App/**/*.js',
                    '!./App/**/*-spec.js'
                ]
            },
            options: {
                alias: {
                    'jquery': './Scripts/jquery-2.1.4.js',

            }
        },
        test: {
