Unmet Peer Dependencies - Can't install package angular2-jwt

[UlyssesAlves]

I'm trying to install package angular2-jwt to my project but NPM is complaining of some unmet peer dependencies. I've cleaned the NPM cache and deleted the node_modules folder but the error still occurs. I've also tried to install the dependencies individually but it complains the same error, so I can't install neither the dependencies nor the angular2-jwt itself.

The errors are as follows:

@UlyssesAlves can you send your package.json prod and dev dependencies?

@leonardobazico It's just a prototype I'm currently working on, so there's just dev dependencies below:

@UlyssesAlves, I'm not sure, but I believe that latest version of angula2-jwt is not compatible with angular RC. So I recommend that you update angular to stable release.

@leonardobazico I got this to work by globally installing rxjs and @angular/cli, as suggested by vicatcu and MAJLGC in this issue.

This may not be a "solution" of course, just a work around. I don't know how the issue could be solved like in the root of the problem, though. For example, instead of having to install these packages globally, maybe there's some adjustment that could be done in the angular2-jwt itself that would allow it to work without changing the development environment.

Nevertheless, by now, installing the packages globally will solve the issue (at least it solved it for me) until the definitive solution is implemented.

This error has been fixed in angular-cli libray, thus I'm closing this issue since it was a calateral effect of that one.
