Gulp-sourcemaps not creating a sourcemap file?

问题:

I'm trying to get Gulp sourcemaps to write files, but I can't see these files anywhere. If any new files were created in the working tree, I would see them in git status, but nothing no new files to be found.

Below is my gulpfile.js

var gulp = require('gulp'),
    sourcemaps = require('gulp-sourcemaps'),
    minify = require('gulp-minify'),
    concat = require('gulp-concat'),
    uglify = require('gulp-uglify');

gulp.task('js', function() {

    return gulp.src('src/js/**/*.js')
        .pipe(sourcemaps.init())
            .pipe(concat('all.js'))
            .pipe(uglify())
        .pipe(sourcemaps.write())
        .pipe(gulp.dest('./public/js'));
});

Is this correct usage? From the examples I've seen elsewhere, this should be OK. I also see that these plugins are compatable with sourcemaps: https://github.com/floridoo/gulp-sourcemaps/wiki/Plugins-with-gulp-sourcemaps-support

回答1:

Using the sourcemaps.write() method the way you do appends a source maps line to the all.js file. If you want to write external source map files, you'll need to pass the path to the sourcemaps.write() method:

sourcemaps.write('../maps')
