Not finding branch dev-master

[seiberdrache10]

I am trying to setup OAuth authentication for Wordpress. After downloading the client-cli by:
$ git clone https://github.com/WP-API/client-cli

I execute:
$ cd client-cli
$ composer install

My composer.json looks like this:

And my terminal outputs the following:

The problem seems to be that I don't find the dev-master branch. I can replace dev-master by an existing branch like 5.2.9 in my composer.json, but the package wp-api/client requires the master branch, as of my understanding.

I also tried adding "@dev" to "dev-master" in the requirements, but that did not change anything.

I am kinda new to this topic, forgive me if I overlook something obvious.

@seiberdrache10 this is likely more an issue using composer. were you able to figure it out so far or do you still need some pointers?

@seiberdrache10 in an attempt to cleanup this repo we are trying to filter the issues and see which ones might be closed. Is it safe to assume this is a rather old issue, which sadly was left unanswered, and can be closed? Feel free to close it yourself with some comments if helpful.
