Popper-core: Again: Uncaught SyntaxError: Unexpected token export

[QJan84]

No matter which file I take, it does not work. I always get the error message.
I downloaded version 1.14.3 via yarn.

All tried but it does not work:
"./node_modules/popper.js/dist/esm/popper.min.js",
"./node_modules/popper.js/dist/umd/popper.min.js",
"./node_modules/popper.js/dist/popper.min.js",

This causes the error:
export default Le;

Can the error be with my gulp task?

// babel js task - transpile our Javascript into the build directory
gulp.task('js-babel', function() {
  $.fancyLog("-> Transpiling Javascript via Browserify & Babelify...");
  $.glob(''+pkg.globs.babelJs+'', function(err, files) {
    if (err) {
      $.util.log($.util.colors.red('Glob error:'),err);
    }
    var tasks = files.map(function(entry) {
      $.fancyLog(entry);

      return $.browserify(entry)
          .transform('babelify')
          .bundle()
          .pipe($.vinylSourceStream($.path.resolve(entry), $.path.resolve(pkg.paths.src.js)))
          .on('error', function(e) {
            $.util.log($.util.colors.red('Browserify compile error:'),e.message);
          })
          .pipe(gulp.dest(pkg.paths.build.js));
    });
  });
});

// inline js task - minimize the inline Javascript into _inlinejs in the templates path
gulp.task("js-inline", () => {
    $.fancyLog("-> Copying inline js");
    return gulp.src(pkg.globs.inlineJs)
        .pipe($.plumber({errorHandler: onError}))
        .pipe($.if(["*.js", "!*.min.js"],
            $.newer({dest: pkg.paths.templates + "_inlinejs", ext: ".min.js"}),
            $.newer({dest: pkg.paths.templates + "_inlinejs"})
        ))
        .pipe($.if(["*.js", "!*.min.js"],
            $.uglify()
        ))
        .pipe($.if(["*.js", "!*.min.js"],
            $.rename({suffix: ".min"})
        ))
        .pipe($.size({gzip: true, showFiles: true}))
        .pipe(gulp.dest(pkg.paths.templates + "_inlinejs"))
        .pipe($.filter("**/*.js"))
        .pipe($.browserSync.stream());
});

// js task - minimize any distribution Javascript into the public js folder, and add our banner to it
gulp.task("js", ["js-inline", "js-babel"], () => {
    $.fancyLog("-> Building js");
    return gulp.src(pkg.globs.distJs)
        .pipe($.plumber({errorHandler: onError}))
        .pipe($.if(["*.js", "!*.min.js"],
          $.newer({dest: pkg.paths.dist.js, ext: ".min.js"}),
          $.newer({dest: pkg.paths.dist.js})
        ))
        .pipe($.if(["*.js", "!*.min.js"],
            $.uglify()
        ))
        .pipe($.if(["*.js", "!*.min.js"],
            $.rename({suffix: ".min"})
        ))
        .pipe($.header(banner, {pkg: pkg}))
        .pipe($.size({gzip: true, showFiles: true}))
        .pipe(gulp.dest(pkg.paths.dist.js))
        .pipe($.filter("**/*.js"))
        .pipe($.browserSync.stream());
});

export default Le; is not part of Popper.js, it must be some of your code.

[QJan84]

Hm, that's not right. Look here: https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/esm/popper.min.js

[FezVrasta]

Oh ok that's the minified ES build, you should use it only if your build tool supports ES modules. Otherwise you should use UMD.

[QJan84]

Thank you! It work's now. My build tool was wrong.
