Encountering JavaScript errors when using Angular 2 RC 7 with gulp

Embark on your journey with gulp and angular today. Running gulp tasks to compile scss and ts files results in errors.

Error: Can't resolve all parameters for PostsComponent:

No errors occur when I compile ts using the following command:

npm run tsc:w

I've been trying to solve this issue all day without any success. It seems like the problem is related to all my services.

Take a look at my gulpfile.js below:

'use strict';

var gulp       = require('gulp'),
    watch      = require('gulp-watch'),
    prefixer   = require('gulp-autoprefixer'),
    sass       = require('gulp-sass'),
    ts         = require('gulp-typescript'),
    sourcemaps = require('gulp-sourcemaps'),
    cssmin     = require('gulp-minify-css');

// Gulp tasks omitted for brevity

gulp.task('default', ['watch']);

This is my posts.component.ts file:

import { Component, OnInit } from "@angular/core"
import { PostsService }      from "./posts.service"
import { PostItem }          from "./post.item"

// Component code omitted

export class PostsComponent implements OnInit
{
    // Constructor and methods omitted for brevity
}

Now let's take a look at posts.service.ts:

import { Injectable } from "@angular/core"
import { Http }       from "@angular/http"

// Service code omitted

@Injectable()
export class PostsService
{
    // Constructor and method omitted for brevity
}

If you have any insights or suggestions, I would greatly appreciate it. Thank you!
