rxjs-5.0.0-rc.4 has not needed @types/chai. https://github.com/angular/angular-cli/issues/3071#issuecomment-259311405 — committed to tmtk75/statusy by tmtk75 8 years ago

@tarlepp It seems rxjs requires @types/chai somehow. I also ran into the same error message and I could solve with this in my case. Hope this helps you as a workaround to suppress the error messages.

npm i --save-dev @types/chai

I think chai is a test framework, so hope rxjs should not include the dependency in the released module.

The solution of @tmtk75 worked for me on RxJS RC5
