E:\Work\angularjs\1ng2-myproj1>npm start

angular2-quickstart@1.0.0 start E:\Work\angularjs\1ng2-myproj1 tsc && concurrently "tsc -w" "lite-server"

Hm. Your error seems to indicate some problem during the npm install. It's basically saying that one of your libs is broken (in this case, angular itself).

Can you delete node_modules and do npm install again? If that's the problem, it should fix it.

[jobyjohnkj]

@filipesilva Thank you ! I deleted node_modules and run npm install. it worked.

[filipesilva]

Awesome :D

[raghuariga]

@filipesilva Thank you !

I have commented main.js

//import { bootstrap } from "@angular/platform-browser-dynamic";

//import { AppComponent} from "./app.component";

//bootstrap(AppComponent);

Added this from https://angular.io/docs/ts/latest/quickstart.html

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; import { AppComponent } from './app.component'; const platform = platformBrowserDynamic(); platform.bootstrapModule(AppComponent);

It worked

what will be the solution for this

[jjorbas]

As vrushali1508 I have the same problem with release 6.0.0-rc.3 and material 5.2.4

Hi @gustavogialim , Did you find any solution ?

[gustavogialim]

Hi @Tataraovoleti I could not resolve with the same packages.

Try to install:

"rxjs": "^6.0.0",
"rxjs-compat": "^6.0.0"

I had the same errors by migration from Angular 5.2.10 to 6.0.0 and It has solved the problem. Here you'll find more information: https://github.com/ReactiveX/rxjs/blob/master/MIGRATION.md Good Luck!)
