Getting a strange error using a basic gulp/express build watch.

Gulpfile.js

var gulp         = require('gulp'),

    minifycss    = require('gulp-minify-css'),
    rename       = require('gulp-rename');

gulp.task('express', function() {
  var express = require('express');
  var app = express();
  app.use(require('connect-livereload')({port: 4002}));
  app.use(express.static(__dirname));
  app.listen(4000);

function notifyLiveReload(event) {

  tinylr.changed({

gulp.task('styles', function() {
    return gulp.src('sass/*.scss')
      .pipe(sass({ style: 'expanded', sourcemap: false }))
      .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1'))
      .pipe(gulp.dest('css'))

  gulp.watch('css/*.css', notifyLiveReload);
});

gulp.task('default', ['styles', 'express', 'livereload', 'watch'], function() {

});

Style.scss

body { position: relative; }

The express server/livereload works fine, but when it tries to compile the stylesheet I'm getting this error (even with sourcemap: false)

• It's pretty clearly telling you that there's something wrong on style.css.map, line 3, char 1. Have you checked your mapfile? – mpowered Commented Nov 17, 2014 at 18:40
• Map file does not exist. It's creating that in tmp, and previously it was autocreated without errors. i'm suspecting this update to sass is relevant but haven't found solution. – elzi Commented Nov 17, 2014 at 18:43
• 3 Removing the pipe to gulp-autoprefixer allows it to build successfully. hmm. – elzi Commented Nov 17, 2014 at 18:49
• getting the same error (without express) – ProblemsOfSumit Commented Nov 19, 2014 at 11:26
• Does the answer I provided below not resolve it for you? – elzi Commented Nov 19, 2014 at 18:03

Disabling sourcemaps is some kind of mystery right now. You have to do it like this

.pipe(sass({ "sourcemap=none": true }))

Source

Not entirely sure why this fixes it, but changing the autoprefixer pipe to:

.pipe(autoprefixer({
     browsers: ['last 2 versions'],
     cascade: false
}))

and putting it before the sass pipe (top) allows it to build succesfully.

I fixed this problem keeping the source maps and using gulp-filter:

var filter = require('gulp-filter')
var filterCSS = filter('**/*.css');

gulp.task('styles', function() {
    return gulp.src('sass/*.scss')
      .pipe(sass({ style: 'expanded', sourcemap: true }))

      // Filters only css files before auto prefixing
      .pipe(filterCSS)
      .pipe(autoprefixer('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1'))
      .pipe(filterCSS.restore())

      .pipe(gulp.dest('css'))
      .pipe(rename({suffix: '.min'}))
      .pipe(minifycss())
      .pipe(gulp.dest('css'));
});

I was having the same issue with the gulp-ruby-sass plugin. I found this blog post which explains that there are a couple of bugs in the gulp-ruby-sass plugin regarding source maps. They have both been closed a little over a week ago. If you upgrade to gulp-ruby-sass~1.0.0-alpha this should fix the issues your having with source maps.

If that doesn't work the article I linked to above shows how to use the gulp-sass plugin which which doesn't have the source map issue.

Try upgrading to gulp-ruby-sass 1.0.0-alpha. It uses gulp-sourcemaps and should avoid all iterations of this problem.
