Typescript+Gulp+Protractor => Cannot find module config.js

I am trying to run the protractor using gulp. I am able to run first two task but when I try to run the third task its not able to find the config.js file which is stored in below path (Windows system)

F:\Selenium2\Protractor\TypeScriptProject\ConvertedJSFiles\config\config.js

gulpfile.js

import * as gulp from 'gulp';
import * as protractor from 'gulp-protractor';

gulp.task('webdriver-update', protractor.webdriver_update);
gulp.task('webdriver-standalone', protractor.webdriver_standalone);
gulp.task('run-prot', function () {
    console.log('About to run the specs...........')

    gulp.src(['ConvertedJSFiles/specs/*.js']).pipe(protractor.protractor({
            configFile: 'ConvertedJSFiles/config/config.js'
    })).on('error',function(e){
            throw e;

    });
});
console.log(protractor.getProtractorDir() + ' is the protractor directory ***');

Console Error

Error: protractor exited with code 105

Issue was with wrong directory reference. I debugged it with "path" package. below is the updated file.

import * as gulp from 'gulp';
import * as protractor from 'gulp-protractor';
import * as path from 'path';
gulp.task('webdriver-update', protractor.webdriver_update);
gulp.task('webdriver-standalone', protractor.webdriver_standalone);
gulp.task('run-prot', function () {
    console.log('About to run the specs...........')
    let srcfiles=path.resolve('../specs/*.js');
    console.log(srcfiles);
    gulp.src([srcfiles]).pipe(protractor.protractor({
            configFile: '../config/config.js'
    })).on('error',function(e){
            throw e;

    });
});
console.log(protractor.getProtractorDir() + ' is the protractor directory ***');
