TypeError: Cannot read property 'reduce' of undefined

Hey, thanks for the library.

I'm having issues using gulp-flatten. I am using

  return gulp.src('./components/**/*.pug')
        // .pipe(print())
        .pipe(flatten())
        .pipe(pug({ verbose : false }))
        .pipe(gulp.dest("./../public/templates/"))

also tried

  return gulp.src('./components/**/*.pug')
        // .pipe(print())
        .pipe(pug({ verbose : false }))
        .pipe(flatten())
        .pipe(gulp.dest("./../public/templates/"))

Both produce the following error:

Hey, @JamesMilnerUK

Sorry for late reply. Could you try following:

gulp.src('./components/**/*.pug')
        .pipe(flatten())
        .pipe(gulp.dest("./../public/templates/"))

Does it work?

I believe you tried using the flatten package, and not gulp-flatten.

npm install gulp-flatten --save-dev

var flatten = require('gulp-flatten');
