gulp tâches ont échoué avec EEXIST erreurs

Ce matin, mon gulp script de construction a commencé à défaut; autre que de faire mon travail habituel dans le répertoire du projet, je n'ai pas fait d'autres modifications à mon système.

J'ai un répertoire /src avec divers fragments de HTML, les images, le javascript, les MOINS, et je suis en utilisant gulp pour compiler/concaténer/copier et de les placer dans le répertoire /web. Le "défaut" l'exécution de la tâche d'une "construction" de la tâche, qui appelle toutes les autres tâches, puis avaler.la montre est mis en place pour regarder les répertoires pour les changements, et d'exécuter la tâche appropriée est un changement est constaté.

Au début de chaque tâche, j'utilise des del() pour nettoyer le dossier de destination. Cependant, lorsque vient le temps de placer le contenu dans le dossier de destination, la tâche échoue avec un "EEXIST' erreur, ou de la tâche se termine bien, et certains fichiers sont au hasard manquant dans le répertoire de sortie.

Voici mon invite de commande qui montre les tâches à défaut au hasard:

Voici le gulp fichier que j'utilise:

rename = require('gulp-rename'),
merge = require('merge-stream'),
del = require('del'),
libraries = [

return gulp.src('src/less/project.less')
.pipe(less())
.pipe(gulp.dest('web/project_files/css'))
});
gulp.task('scripts', function() {
del(['web/project_files/js']);
var libraryStream = gulp.src(libraries)

});
gulp.task('images', function() {

return gulp.src('src/img/**/*.+(jpg|png)')
.pipe(imagemin({optimizationLevel: 3, progressive: true, interlaced: true }))
.pipe(gulp.dest('web/project_files/img'))
});
gulp.task('fonts', function() {

return gulp.src('src/fonts/**/*.+(eot|svg|ttf|woff|otf)')
.pipe(rename(function(path) {

.pipe(gulp.dest('web/project_files/fonts'));
});
gulp.task('html', function() {
del(['web/project.htm']);
del(['web/project_files/templates']);
var htmlStream = gulp.src('src/html/index.html')
.pipe(fileinclude())
.pipe(rename('project.htm'));
var templateStream = gulp.src('src/html/templates/**/*.html')
.pipe(rename(function(path) {
path.dirname = "/project_files/templates/"+path.dirname;
path.extname = ".tpl";
}));
return(merge(htmlStream, templateStream))
.pipe(gulp.dest('web'));
});
gulp.task('build', ['styles', 'scripts', 'images', 'fonts', 'html'], function() {
});
gulp.task('default', ['build'], function() {
gulp.watch('src/html/**/*.html', ['html']);
gulp.watch('src/less/**/*.less', ['styles']);
gulp.watch('src/js/**/*.js', ['scripts']);
gulp.watch('src/img/**/*.+(jpg|png)', ['images']);
gulp.watch('src/fonts/**/*.+(eot|svg|ttf|woff|otf)', ['fonts']);
});

Le message d'erreur indique l'emplacement de destination existe, mais elle ne devrait pas (del) en enlevant le répertoire de destination au début de chaque tâche enfant?

Mise à JOUR:

Ici est la façon dont je structure mes tâches à maintenant, ce qui semble être de travailler vite et correctement:

gulp.task('scripts', function() {
del(['web/js'], function(err) {
if (err) return;
return gulp.src('src/js/**/*.js')
.pipe(concat('mything.js'))
.pipe(gulp.dest('web/js'));
});
});
