Right way to upgrade RxJS to latest version?

When trying to install the latest version of RxJS,

I used npm install rxjs as explained in this documentation: https://github.com/reactivex/rxjs

But I got these warnings:

npm warn @angular/[email protected] requires a peer of rxjs@^5.5.0 but none is installed.

You must install peer dependencies yourself.

enter image description here

So it looks like RxJS is upgraded but not to the latest version.

In the output we see that there is a latest one which is RxJS 5.5.0

Is there any better npm command line to upgrade to the latest version ?

EDIT 2020

The easiest way to force upgrade any package would be to do append an @latest to the required package.

In our use case it would be 

npm install rxjs@latest

This would force your current setup to install the latest stable version available.

Bear in mind that the latest version might not always be compatible with all the libraries in use. In case a specific range is needed due to compatibility issues you should install specific versions(e.g for the use case)

npm install [email protected]

In the previous answer it was also included the -g flag. This would (as for any npm package installation) install the specified package globally in your system and not only on the current project

Previous Answer

You can always try to force the version by doing 

npm install -g [email protected]

Or you can have a more modern approach and use yarn :)

NOTE

Since the release of npm 5.x the comment about yarn is no longer necessarily true :)

There seems to be some problem with the latest rxjs. You can change to another rxjs version as given below:

npm install [email protected] --save

Npm is telling you that it has found latest version 5.5.0 but your angular 5.1 version is not compatible with [email protected] and hence it falls back to the last compatible. Upgrade your angular version alongside, so that you can leverage features of both You can install latest angular using npm install -g @angular/cli@latest After installation you will need to run npm update in your project
