I am trying to upgrade my angular4 app to angular 5 by using npm-check-updates.
I ran below three commands:

```
npm install -g npm-check-updates
ncu -u
npm update

```

After that i tried to run up the app using my command: 
 npm run serve

My package.json looks like this:

```
"scripts": {
"ng": "ng",
"start-ng": "ng serve",
"start": "node src/server/index.js",
"build": "ng build",
"build-dev": "ng build -dev",
"build-local": "ng build -dev -e local",
"build-test": "ng build -prod -e test",
"build-prod": "ng build -prod -e prod",
"serve": "ng serve -dev -e local -o",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"sme": "./node_modules/.bin/source-map-explorer"

```

},

I am unable to run up the app as i am getting below mentioned error:

```
