error thrown when trying to delete a file that is gone.

[bcowgill]

gulp-clean gets the listing of files to delete:

build/x build/x/this.js

it seems the deletion of build/x gets rid of everything and when clean tries to delete build/x/this.js it gives an error. WHY? it's already gone! Perhaps clean should sort the list in reverse length order before doing its work or have an option to ignore / warn on files that are missing.

[bcowgill]

note, was using 'build/*/' as the match pattern. switching to just 'build' solves the immediate problem.

I have a related problem -- I'm using Gulp 4, I'm trying to call delete on a directory that may or may not be present, and I'm getting:

[15:13:00] Error: File not found with singular glob: /home/pat/gop/src/github.com/nullbio/lolwtf/dist/public/assets/

The dist folder in my glob there that you can see (and naturally all of its subfolders) have the potential of not being created yet.

Is there some way I can ignore the error message, or prevent it from happening? I tried on('error'), but that doesn't seem to get fired.

It's been a while since I have touched this, but as quite a few are clearly still using gulp-clean, I'll try to be more active.

it seems the deletion of build/x gets rid of everything and when clean tries to delete build/x/this.js it gives an error.

@bcowgill I created a similar case as yours:

'use strict';
const gulp = require('gulp');
const clean = require('gulp-clean');

gulp.task('clean', () => {
  return gulp.src('build/**/*')
    .pipe(clean());
});

I can confirm that filepaths gulp-clean receives are the ones you mentioned:

• build/x
• build/x/this.js

But in my case the cleaning works and gulp-clean does not emit errors:

$ node -v
v9.3.0
$ gulp -v
[21:29:52] CLI version 2.0.0
[21:29:52] Local version 4.0.0
$ gulp clean
[21:29:56] Using gulpfile ~/gulpfile.js
[21:29:56] Starting 'clean'...
[21:29:56] Finished 'clean' after 45 ms

Why it actually works, is because of rimraf handles ENOENT errors behind the scenes and returns successfully. Thus even when gulp-clean tries to remove a file which does not exist anymore everything should work nicely. See the rimraf README.

@bcowgill can you provide a reproducible example of your problem? Thanks.

@nullbio I am not sure your case actually relates to gulp-clean as gulp-clean does not try to find files with a glob. Most likely this happens already before the execution comes to the gulp-clean plugin. But to be sure could you provide more details or a simplified example where your error occurs? Thanks.

I know that this is kinda old thread, but for those who are facing @nullbio problem with gulp 4: passing allowEmpty: true to gulp.src should solve the problem.

gulp.task("clean", function() {
    return gulp.src("./dist", { read: false, allowEmpty: true })
        .pipe(gulpClean());
});
