使用Gulp -gzip时，Gulp SourceMaps不工作

Question

我使用Gulp来丑化javascript文件并生成它们的源映射。一切顺利:

var gulp = require('gulp');
var plugins = require('gulp-load-plugins')();
gulp.task('compress-js', ['clean-js'], function() {
  return gulp.src('./resources/js/**/*.js')
    .pipe(plugins.sourcemaps.init())
    .pipe(plugins.uglify())
    .pipe(plugins.rename({extname: '.min.js'}))
    .pipe(plugins.sourcemaps.write('./maps'))
    .pipe(gulp.dest('./public/js'))
    .pipe(plugins.livereload());
});

这段代码生成了以下输出文件夹和文件，它们被浏览器正确加载:

公共/js/someScript.min.js

function doSomeStuff(){console.log("This stuff function simply says: hello!!")
//# sourceMappingURL=maps/someScript.min.js.map

公共/js/地图/someScript.min.js。map:注意这个文件在上面的行中被引用。

然而，我也想gzip他们，所以我更新的gulpfile.js是:

gulp.task('compress-js', ['clean-js'], function() {
  return gulp.src('./resources/js/**/*.js')
    .pipe(plugins.sourcemaps.init())
    .pipe(plugins.uglify())
    .pipe(plugins.rename({extname: '.min.js'}))
    .pipe(plugins.sourcemaps.write('./maps'))
    .pipe(plugins.gzip())
    .pipe(gulp.dest('./public/js'))
    .pipe(plugins.livereload());
});

现在我得到这些文件:

公共/js/someScript.min.js.gz

function doSomeStuff(){console.log("This stuff function simply says: hello!!")}
//# sourceMappingURL=maps/someScript.min.js.map

公共/js/地图/someScript.min.js.map.gz

源映射没有被链接，因为js.gz文件引用了someScript.min.js。someScript.min.js.map.gz。我错过了什么?我如何使文件引用正确的扩展名?

我设法通过重命名生成的地图文件来解决这个问题，删除。gz扩展名:

gulp.task('compress-js', function(cb) {
  gulp.src('./resources/js/**/*.js')
    .pipe(plugins.jshint())
    .pipe(plugins.sourcemaps.init())
    .pipe(plugins.uglify())
    .pipe(plugins.rename({extname: '.min.js'}))
    .pipe(plugins.sourcemaps.write('./maps'))
    .pipe(plugins.gzip({ append: true }))
    .pipe(gulp.dest('./public/js'))
    .pipe(plugins.livereload())
    .on('end', function() {
        postProcessMapFiles('./public/js/maps/**/*.map.gz', './public/js/maps', cb);
    });
});
function postProcessMapFiles(compressedMapFiles, publicDir, cb){
    gulp.src(compressedMapFiles)
       .pipe(plugins.debug())
       .pipe(plugins.rename({extname: ''}))
       .pipe(plugins.debug())
       .pipe(gulp.dest(publicDir))
       .on('end', function() {
          del([compressedMapFiles], cb);
       });
}

我已经把地图文件gunzip了。

var gunzip = require('gulp-gunzip');
// this task will depend on task sass, that generates the problem
gulp.task('uncompress_map', ['sass'], function () {
    var maploc = 'src/build/maps';
    return gulp.src(maploc+'/*.gz')
        .pipe(gunzip())
        .pipe(gulp.dest(maploc));
});
