npm - The package rxjs@5.0.0-beta.6 does not satisfy its siblings' peerDependencies requirements? -

-

i trying install @ngrx/store module in angular 2 app. using npm install , getting following error:

npm err! peerinvalid package rxjs@5.0.0-beta.6 not satisfy siblings' peerdependencies requirements! npm err! peerinvalid peer @angular/core@2.0.0-rc.0 wants rxjs@5.0.0-beta.6 npm err! peerinvalid peer @angular/http@2.0.0-rc.0 wants rxjs@5.0.0-beta.6 npm err! peerinvalid peer angular2@2.0.0-beta.16 wants rxjs@5.0.0-beta.2 npm err! peerinvalid peer @ngrx/store@1.5.0 wants rxjs@5.0.0-beta.6

does mean have upgrade angular2 module because needs lower version of rxjs@5.0.0-beta.2?

the problem have both beta.16 , rc.0 dependencies in same project. since angular changed npm package name between two, need uninstall , remove dependencies on whichever 1 don't want. assuming want upgrade rc.0, remove package.json , run:

npm uninstall angular2

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
