Current behavior

ng serve or ng build showing the below described error.

Expected behavior

ng serve should start the application at localhost:4200

Minimal reproduction of the problem with instructions

I created one application using ng new appname and then in my package.json I changed ^2.4.0 to 4.0.0-rc1 to upgrade from angular2 to angular4. Then I deleted the node_modules and did npm i to get dependencies. everything goes well.

Now when I did ng serve ot ng build I got below error.

angular cli version
@angular/cli: 1.0.0-rc.0
node: 6.9.1
os: darwin x64

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 2.0.X

• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

• Language: [all | TypeScript X.X | ES6/7 | ES5]

• Node (for AoT issues): node --version = 6.9.1

[DzmitryShylovich]

You need to generate a new project using --ng4 flag:

ng new appname --ng4

[naveedahmed1]

@DzmitryShylovich solution should fix the issue. I would also suggest updating to the latest release of angular-cli.

[Toxicable]

While that flag should fix it, the reason for this issue is that you havn't upgraded your TypeScript to version 2.1.x

[robwormald]

upgrade your version of Typescript. Closing.

[aniruddhadas9]

@Toxicable @robwormald By upgrading from Typescript ~2.0.0 to ~2.1.0 resolved my issue. thanks :)
@DzmitryShylovich actually I was upgrading my existing app from 2.x.x. to 4.0.0-rc1 but did not try a new project creation with --ng4. @naveedahmed1 I am using the latest version of cli 1.0.0-rc0 and upgraded angular 2.x.x to 4.0.0-rc1 directly changing the version in package.json.

[naveedahmed1]

@aniruddhadas9 I believe with --ng4 you dont need to update package.json manually.

[aniruddhadas9]

@naveedahmed1 true. I am upgrading my developed application. Its not a new application I am creating.
