When trying to use Jasmine types definition in awesome-typescript-loader for webpack i'm getting the following error

[at-loader] ./node_modules/@types/jasmine/index.d.ts:314:15
TS2428: All declarations of 'Matchers' must have identical type parameters.

FIXED:

So angular documentation tells you to use a helper method for testing:
declare namespace jasmine {
interface Matchers {

}
}

Since Matchers now strongly types it needed to be changed to

Hi Jordan ,
Above soln did not work for me.Could u please elaborate what i need to change in Matchers Interface?

[paullryan]

@manindersoprasteria You need to update your

declare namespace jasmine {
  interface Matchers {
  ...

to

declare namespace jasmine {
  interface Matchers<T> {
  ...

@manindersoprasteria you'll also need @types/jasmine version that has that change for the Matchers interface (e.g. =< 2.6)
