ReferenceError: buffer is not defined

I get this error

/Users/username/Sites/process images/node_modules/imagemin-jpegtran/index.js:61
            if (err && (err.code !== 'EPIPE' || !isJpg(buffer))) {
                                                       ^

every time I run this script

gulp.task('imagemin', () => {
    return gulp.src('src/**/*')
        .pipe(plumber({
            errorHandler: function (err) {
                gutil.beep();
                console.log(err);
               // this.emit('end');
            }
        }))
        .pipe(changed('dest'))
        .pipe(remember('all'))
        .pipe(imagemin({
            optimizationLevel: 2,
            progressive: true,
            svgoPlugins: [{removeViewBox: false}],
            use: [pngquant()]
        }))
        .pipe(gulp.dest('dest'))
        .pipe(cache('cache1', {optimizeMemory: true}))
        .pipe(remember('all'))
        .pipe(cache('cache1', {optimizeMemory: true}))
        .pipe(gulp.dest('dest'));
});

When the updated version will make it's way to NPM? Current v.3.3.4 doesn't include this update.

Released as v4.3.2. 0e6a658

I type npm update imagemin-jpegtran, then npm -v imagemin-jpegtran and see 3.3.4. What do I do wrong?

That's not an issue with imagemin-jpegtran.
