由于嵌入路径,在VS代码中找不到源映射

我有一个使用gulp构建的角度应用程序。与大多数Angular应用程序一样,代码是用TypeScript编写的,然后编译成Javascript。
生成的Javascript文件位于TypeScript文件之外。源地图文件也位于同一文件夹中。
当我在Chrome中打开控制台并导航到其中一个Javascript文件时,Chrome告诉我它能够检测源地图。
当我试图从VS代码中调试应用程序时,它会告诉我:

未验证断点,由于未找到生成的代码而忽略断点(源代码映射问题?)

现在,我做了一些挖掘,源地图包含以下标题:

{"version":3,"sources":["app/lib/_common/equipment/components/equipment-selection/equipmentSelection.component.ts"]

源映射文件不包含 sourceRoot . 如果我编辑源映射并删除路径,只保留文件名,VS代码可以加载源映射并正确调试:

{"version":3,"sources":["equipmentSelection.component.ts"]

我需要在配置中更改什么才能生成正确的源映射?

gulp.task('typescript', ['lint'], () => {

    let sourcemaps = require('gulp-sourcemaps'),
        ts = require('gulp-typescript'),
        merge = require('merge2');

    let tsProject = ts.createProject('tsconfig.json');

    let tsResult = tsProject.src()
        .pipe(sourcemaps.init({}))
        .pipe(precompileNgx())
        .pipe(tsProject())
        .on('error', function () {
            gutil.log(gutil.colors.red("*** THERE IS AN ERROR IN YOUR TYPESCRIPT FILES ***"));
            gutil.log(gutil.colors.red("The code will not compile until this is fixed!"));
        });

    return merge([
        tsResult.dts.pipe(gulp.dest('./' + libPath)),
        tsResult.js.pipe(sourcemaps.write(".", {includeContent: true}))
            .pipe(gulp.dest('./'))
    ]);
});
