Gulp giving error on symlinks in gulp.src()

I have a symlink in my images folder that points to another folder containing external images provided by a third party library (managed by bower - gotta love javascript). As part of my build process, I compress all images as follows:

gulp.task('images', function() {
return gulp.src('static/img/**/*')
    .pipe(imagemin({ optimizationLevel: 3, progressive: true, interlaced: true }))
    .pipe(gulp.dest('dist/img'))
});

When gulp gets to the symbolic link folder in the img folder, it returns 

events.js:72
    throw er; // Unhandled 'error' event
          ^
Error: EISDIR, read

Using gulp-debug shows that it baulks on the symlink folder. I am on Mac OSX and the symlink was created using ln -s. Any ideas?

Solution

  • gulp.src() uses node-glob, which doesn't crawl symlinks:

    ** If a "globstar" is alone in a path portion, then it matches zero or more directories and subdirectories searching for matches. It does not crawl symlinked directories.

    Note that symlinked directories are not crawled as part of a **, though their contents may match against subsequent portions of the pattern. This prevents infinite loops and duplicates and the like.

    I don't know if it's supposed to error or just skip them.
