I'm new in Typescript/Angular2 languages. I'm trying to develop sample application from a Typescript book but I always get the following error:
No provider for RuntimeMetadataResolver (ComponentResolver -> RuntimeCompiler -> RuntimeMetadataResolver)
in the browser console. I think the problem is in component version in packages.json. Angular2 has been installed using npm install so the version is 2.0beta17.

Then I run "gulp", I load the index.html in the browser and I get that error.
I have a node_modules folder created dynamically which contains an angular2 folder...
Thanks in advance.
EDIT: I checked my index.js generated file and
var RuntimeMetadataResolver = (function () {
is present. Moreover,
exports.COMPILER_PROVIDERS
contains
__small$_xxx.RuntimeMetadataResolver
EDIT2: No error in npm ls
command
This appears to be not an issue with Angular, nor TypeScript, but the module bundler Small had a bug. A file a/b
could be compiled twice (under conditions), namely as a/b
and a\\b
. This only happened on Windows. This broke some functionality of Angular. Can you try to update to small@0.2.8
?
Try to upgrade from beta to latest version of angular and try.
Try using "npm update"
you should import it in the root module class according to the documentation . In your case it should be:
@NgModule({
imports: [ BrowserModule, RuntimeMetadataResolver],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
